Definitely the best tutorial I've seen for this stitch - I was struggling to work it out for a while and no other videos I've looked at were quite this helpful so finding this was perfect :)

Thank, this is the best demonstration of garter mattress stitch I've seen.

thank you so much for this great video tutorial. i am currently using mattress stitch to join a pillow - but one side is garter and the other stockinette. after watching your tutorial i think i can now do a better job in joining my pieces together :)

Very clearly explained; thank you! However, I'm not clear on what to do when you reach the end of the square (I'm a new knitter)? Do you weave in the remaining yarn, or...? How do you keep the knitted seam from unraveling? Thanks so much!

Thank you for such a clear and easily understood tutorial on this stitch.

Smiles and frowns. I get it! Thank you.

Very well explained and demonstrated. Thanks.

thanks for the clear demonstration :)

Great clear instructions!

Good video, thank you.

How would I do this to join shoulder seams? I understand the vertical (side) instructions, very nice thank you.

This is wonderful! Thank you for sharing!

Thanks for such a good video!!!

Excellent tutorial, thank you!

I have to sew a Crossover collar into square neckline which entails sewing through 3 thicknesses of wool then ease in the rest of the neck and collar in together. What stitch do I use for the three thicknesses

Another great tut!! Thanks ...

Would you use this same technique if your edges are slipped stitched

Thank you so much! Tried to "invent" this myself and it was NOT nice.
