How to Upcycle a T-Shirt into a Cardigancomments (35) November 2nd, 2012
I decided five rows was just right for my buttons, but you might want more or less. When yours is wide enough, finish off and weave in the ends.
4. Now comes the "buttonhole side" of the placket. Join onto the right side of the placket and crochet two rows just as you did for the other side. Next, you'll need to measure the length of the placket and divide it by the number of buttons you plan to use. Place stitch markers (or safety pins) where you want each hole.
Also measure one of your buttons against your stitches to determine how many stitches wide each buttonhole should be. Mine are three-stitch holes. The row you make the holes in should be the center row of your placket. Mine is five rows wide, so I put the holes into the third row. If you are using an even number of rows, put the holes in the row after the halfway point (so for six, use the fourth row). To make the buttonholes, sc up to the beginning of the hole, chain the required number of stitches (I did three)...
...skip the same number of stitches, and sc into the very next stitch (in my case, the fourth).
