Currently knitting up the most delightful looking February Lady Sweater and have learned the most wonderful way to make a buttonhole!
Previously, the only way I knew how to make a buttonhole is to do a yarn over. Which essentially means that my buttonhole is limited to the size of two stitches, which therefore does not allow for bigger sized buttons if one wished.
Cue the wondrous buttonhole (with easy to follow instructions).
And in essence, it's a matter of binding off and casting off again. Neat, tidy, more or less reversible, makes no adverse impact on the garment and best of all, the buttonhole can go for as big as you want it too.
