Continue slipping off stitches and binding off if you are making a larger buttonhole. For small buttonholes, you may only need to bind off a couple of stitches. But for larger button holes, you will need to bind off more stitches. Keep going until the button hole is the length that you need it to be. [3] X Research source
Cast on as many stitches as you bound off. For example, if you bound off four stitches, then cast on four stitches.
If you only needed one buttonhole, then knit to the end of the row. If you need more than one buttonhole, then knit until you reach the next space for placing a buttonhole and repeat the process again.
Continue binding off by knitting one and pulling the first stitch over the second stitch. Continue to bind off as many stitches as you need to create your buttonhole.
For example, if you bound off three stitches, then you will need to cast on three stitches.
Try holding up the buttons against the buttonholes as you create them. This will help to ensure that you do not make them too large or too small.
You can also mark the placement spots with a small safety pin or paper clip.
