There was a young women who created a shoe, it flashed in all colours from red, green to blue.

this method would be perfect for a baymax cosplay!

YES!!! Sean looks so majestic in the Power Treads! twitter.com/day9tv/status/1033461745304522752 Here’s a video of Day[9] tread switching like a pro: twitter.com/TorteDeLini/status/1033447064653295616 Here's Sean after the convention talking about wearing the Power Treads: kzfaq.info/get/bejne/j5hlq72GqtGnYqs.html For more prop and costume making knowledge, check out our website! punishedprops.com

Britt, I think you got the 'short-straw' on that build. I've had those jobs where every step presents its own problem. 100 outta 10 for even having a go & congratulations on climbing that learning curve without 'spinning off'. I'll bet there are some very 'juicy' outtakes. Well done!

It my job to make 10ft by 20ft ish inflatable sculpture out of PVC. To say this is the first time you'd done this you did a very good job! There's a real nack to seaming in this manner. Our templates are all cut with a half inch seam allowance and we mask off to allow for that seam to be glued. We use a bostik product which allows us to glue both sides, let each dry and then glue the glue together in smaller sections. Instead of gluing the two pieces of fabric on the same side we glue one on the shiny and one on the dull and this creates a flat seam and allows us to just lay the two pieces atop one another meeting reg marks. It's not perfect, we do still get punctures so similarly to you we do use a continuous air supply. I loved your use of connectors on the inside to create space for a human as it's not a technique we use and expanding my knowledge of pneumatic craft is great! If you decide to pursue more pneumatic costumes I'd be happy to provide photos of how we work!

"Check it out! I'm a shoe!!!" Wow - an epic build with a great outcome. Way to think outside the box all the way through.

What an amazing project, so much time and attention to making sure it gets as close as possible to a functional, comfortable outfit and never giving up when something fails or doesn't work out. Such dedication for something that's probably only going to get a few hours use in the real world before falling apart, but the joy and laughter it brought at the IT and online was totally worth it. Love how these full body trans-formative cosplays really bring the "otherworldly" nature of conventions to life, it really makes them sensational places where you never know what crazy costumes you might find.

This is almost identical to something I've done in a sculpture class. Instead of vinyl, we used plastic drop cloth. Dyed the plastic drop cloth the same way, then used both an iron and a hair straightener to create seams. But make sure you use tin foil between your iron and the plastic or you'll melt it to the iron. My group created a 22 foot tall bottle this way, inflated it with a box fan to its full height and even got inside it like a weird bounce house.

I love that you show the mistakes that go into getting it working in the end, too. As someone who’s also working things out as they go, it’s immensely encouraging. Thank you!

Bravo! Well done, love the level-headed keep on moving forward vibe of this build. And also the fur movement, when you walk, is fantastic!

I love seeing the learning process. The dye changing over time? I wouldn't have thought that either. Now I would!

This makes me so happy. What an unusual build! I never would have thought of that

What a brilliantly mad project! Loved watching the build video :D

I have ironed plastic drop cloth from the hardware store together. I wonder if that would work for vinyl as well. It makes a very strong bond. One KZfaqr filled a giant pouch made of this plastic with water for his kids to play on, so the seem will take some pressure.

I saw Day9 tweet a picture of this and I was like damn that’s pretty cool. No idea you made it, that’s so crazy

Great build. I was wondering if creating a shoulder strap harness would make it easier to carry it. Definitely one of my favorite builds to watch. I laughed so much and my mind kept thinking of how I would handle the build. As always BRILLIANT!!!

Printing the pattern on vinyl like a vinyl banner would have saved you time and coloring. Intrigued to see how it would turn out. This is still REALLY cool!

"DAYS GLITTER FREE" too accurate it hurts. I'm pretty sure they don't have to change it often 😂😂😂

Britt, you really made this the most difficult way you could. Any inflatable that is not hooked to a large fan should be built as a collection of inflatable ribs. You could have made life so much easier by buying some large inflatable pool rings to make the cylinder around the person, with curved tubes making the rest of the frame. I first build using pool noodles and then create the inflatable ribs around them. It does mean that you have to inflate multiple ribs, but this means less pressure and even if one fails the whole structure does not collapse. You can then skin the ribs in any lightweight material.

If the shoe fits wear it !!!! Great build

That was great! I had been wondering about some inflatables and this was full of great ideas. I think I would have gone with suspenders instead of hand straps to carry it around, though.

I was watching this as I was thinking about how to finish the assembly for my infinity gauntlet! I kept thinking I needed some super strong adhesive, but when you mentioned hot glue, a light bulb lit up. Sometimes all you need is the simple stuff!

How come that Brit is so adorable all the time?

Viny is not a thermo-formable plastic. Therefore it is not a good candidate for head bonding. Polyethylene is what you want to use for that. I haven't tried a heat sealer on a large product. But, the small battery operated ones may work. Search "Battery heat sealer" or "handheld heat sealer".

Very instructive. Love it

This was really cool! Great job guys.

Too funny. I’m so glad it all worked. Looks like he had a blast with it!!!

Love the hosts enthusiasm inthe intro

Great work, two shoulder straps may have worked really well for this costume but you knocked it out the park!

Super cool build!

I love the idea of cosplaying an item, it never occured to me xD And the project has a number of interesting strategies, I like it a lot! :D

This is so beautifully ridiculous I wish I could like it more than once. Also I admire your bodging skills.

That turned out great. I've done a bit of hot air welding at a previous job but we were using heavier polyurethane. Not sure if that vinyl would be to thin and just burn through. It takes a fair bit of practice to get the temperature and speed just right.

thank you very much!!! an excellent tutorial on how to start small concept and take it to large scale. this is a great "how to". BTW the people that thumbs down this video are the apparent inflatable costume maker's guild. hahah but i totally laughed outtloud(not the fake LOL) when you got stuck backwards in the shoe @12:00 minute mark !!!

I haven't even played DotA 2, but I NEED this!

Late to this party, but for heat welding you basically need an upscaled heat sealer from a vacuum food saver device. Basically a board with nichrome wire attached and covered in kapton tape and another board to apply pressure. Alternately I have seen hand held devices for resealing crisp packets that might also work, though they may not be powerful enough for this type of vinyl.

This is fantastic!

It was absolutely awesome.

I have tryed both heath welding and adhesive welding and in my opinion adhesive works better. Great video!

lol, that's awesome!!!!!!!!!!!!!! Add that to the resume, "Built giant goofy inflatable light up shoe." Very well done!

Love The Crow "fire it up" reference!!!

When you ran away in the shoe I collapsed 😂

Speaking of templates. I bought the helmet base template for my cosplay next month, it helped a lot! Thanks! I'll post photos on the FB page

Awesome job! 👍👊

I used a heat press for my heat welding however it was a little limiting because the press could only accommodate straight edges. The sweet spot was around 300 degrees for 20ish seconds without it damaging the vinyl too badly.

I have the past made custom seat covers from polyethylene vapor barrier, welding the seams with a clothes iron. The iron works but it's not ideal, I believe a heat sealer for plastic bags would be a much better option, but I've never tried it.

looks amazing so ambitious

This is amazing! You are amazing!

I wonder if you could use a steamer too heat weld the vinyl pieces together.

Props to Brit for not quitting like most people would!!!

What a great artwork there

Great Build! Totally ridiculous but great.

So you were the one to make it, It was so cool seeing it on the arena

This is truly excellent.

Wow that was a ton of work. Great video. : )

freaking amazing!!

WOW!!!! This is so cooool!!!

I made an inflatable costume for Halloween. I chose to be Erik Cartman from South Park, in his police uniform. I wanted something with an oversize head, that wouldn't sit on my shoulders, but extend down to my elbows, making it appear as if his shoulders began there. The rest of the body would be shortened, so his legs would begin at my knees. To understand this idea better, just hold a coat in front of you at your rib cage. Your legs are only visible to the knee, and only your forearms go into the sleeves. Now imagine the upper half of your body inside of a ball. The top of your head is at the top of the ball. I've never seen anyone attempt this shape before, so It was a challenge. Erik Cartman's sunglasses provide plenty of room to see out. My first attempt was with foam and stretchy fabric. I enlarged two beach-ball patterns using an overhead projector as you did. One ball was for the head, of course, and the other ball was for the body. I didn't actually use a coat. I only mentioned it to describe the silhouette I wanted. My legs would poke out of the bottom. But as you mentioned, it was too bulky to transport. So I remade the costume to be inflatable. I bought a battery-powered inflatable costume fan, (which would have to run constantly to keep the costume inflated), and used lightweight nylon material for the costume. I found rip-stop material works best. All seams were machine sewn with lightweight thread, and I had to figure out how to enclose everything. Arms and legs included. Instead of putting a zipper in the back, I kept it in front of the coat. (It had to be long, so it's designed for a sleeping bag.) I did have to add suspenders inside for extra support. After all, there wasn't enough air pressure to keep the perfect balloon shape. But it definitely filled out nicely. Not too bad for my first try: scontent.fric1-1.fna.fbcdn.net/v/t1.0-9/13495283_1390611940968497_3111558822599860299_n.jpg?_nc_cat=108&_nc_sid=8024bb&_nc_ohc=9uVMVzdfE9wAX9GnIVs&_nc_ht=scontent.fric1-1.fna&oh=dfbdaeea1293f80846f94e4ddac9deb8&oe=5EA4F8F3 scontent.fric1-1.fna.fbcdn.net/v/t31.0-8/p720x720/14706925_10206900710268347_7041195029016182573_o.jpg?_nc_cat=100&_nc_sid=d4cf07&_nc_ohc=ccfKUHDYQjcAX9CZin7&_nc_ht=scontent.fric1-1.fna&_nc_tp=6&oh=4e27e43f2459ff2ccc41fe2218af0777&oe=5EA56CA0

Yeah, I haven't been able to get heat welding to work at home yet either. I think we all need more heat and more pressure but I don't know.

We used that same silver fabric for my sons Danny Phantom costume

This is amazing!!!!

so good

That was perfect you’ve did a amazing job

great video, my wife uses a Portable Plastic Bag Food Storage Package Heat Seal Sealer Closer, for all her bags etc. it works very well

O.. M.. G.. this is so funny! Great build! Lol The concept drawing was amazing! Lol

Next Patch notes: Reversed the buckle on the Power Treads artwork.

cool!!

pool toys are ultrasonic welded, not heat welded.. this uses an ultrasonic horn two small shaped metal pieces which pinch the plastic together and then use ultrasonic vibration to cause the plastic to heat and weld together.... en.wikipedia.org/wiki/Ultrasonic_welding

what a hero truly need

you're brilliant

I had an idea to make a dark souls 1 mushroom inflatable costume i was going to modify an existing design or make my own completely..not sure yet but if i do this is going to be my guide of how to more or less modify or create a new One

I like inflatable costumes but when they stay inflated like how Hollywood did “Aunt Marge Inflation” Behind the scenes. Also like the Inflatable Spy Kids 2 Suits, Violet Beauregarde. I wanted to picture myself in how I’d look so Big & Round. You know with that little tube rafts and beach balls have on them I would like a system to inflate certain parts of my body at once

awsome

Could you put the cost of these builds, I really want to know just how much you spent on it

You should try using walnuts to dye, it smells a bit but the color and stain is amazing

That is Ridiculous and awesome

Hey Brittany, could you make a Bayonetta costume soon, cause you two share kind of a resemblance, and because her character design is awesomely badass. Please?

Totally got a kick out of this video... Sorry, I'll show myself out... ;)

Hey Bill and Britney, would you guys be able to make a tutorial on stencil making? Say you're tracing an image in whatever program and want to print it but it's larger than a letter sheet of paper. I've looked and there are weird ways to slice up the image to print and reassemble later but they're kinda outdated. And yes I know you can print things out large scale at UPS but it would be nice to be able to do it at home. Any help would be great. Thank you and fun video! Good job Britney

I’m trying to make a Regigigas one

did anyone try this? did it work?

I'm waking up seing that in my alerts... Well. 😂

I’ve been looking forever for the white carbon fiber fabric by yayahan but I can’t find it anywhere online or in stores, HELP?!???

what doing if you want make a anthropomorphy character?

This is great! XD

The link to the vynil glue just takes me to a search with PVA glue or glue for other materials. Would these work or does it have to be vynil glue? Also, if it does have to be vynil glue, could I have a direct link to some? Thank you in advance!

Small heat welding Machines aren't that har to find. It's used by small manufacurers and shops for making small batches of product packages. Jyst don't burn yourself if you get one! Even on the lowest heat setting they are suuuper hot!

!.! I can see this as part of a Deadpool Cosplay. Just need to change it from a normal boot to a Sentinel foot like from his video game.

DAS BOOOOOOT!

Day9 FTW

A hand held steamer can heat weld vinyl.. found out by accidentally welding a shower curtain while trying to steam clean the shower with a $30 steam cleaner.

Excellent work, but the buckles (if they were real) would fall open. Compare them to a belt buckle, the stud that goes through the belt goes the opposite way to the flappy end of the belt.

Music ?

You should do a tie fighter like this

Could you do a foam latex tutorial??

When I saw this all I can think about doing was cosplaying mario with the goomba shoe from Super Mario Bros 3

"A big fluffy sausage" 14:14

gee-zowie ... too funny ! :-)

I’m early! P.s. Love you’re vids! Keep up the good work!

Damn, Daniel.
