This a knitting tutorial for knitting a buttonhole. I am working it for 5-stitches, but you can use more or less depending on the size button you have and your gauge.
Move working yarn to the front of your work, slip 1 stitch purlwise, return yarn to the back, *slip 1 stitch, pass first slipped stitch over the 2nd to bind off 1 st; rep from * until you have bound off 1 less than the total amount of stitches for the size buttonhole you are creating. (So for this video, I bound off 4 stitches to create my 5-stitch buttonhole.) Slip the last stitch on your right-hand needle over to the left-hand needle and turn your work. With the wrong side facing you, cast on the total number of stitches of your buttonhole, for me this was 5 stitches, using the Cable Cast On method, BEFORE placing the last of the new cast on stitches onto the left-hand needle, bring your working yarn to the front of your work, then place the new stitch on the needle, turn work. Slip 1 stitch knitwise, pass the last stitch that was cast on over the slipped stitch and off the needle. Your buttonhole is complete!
