Buttonhole
A buttonhole is a small opening knitted into a button band, made by binding off a few stitches and casting on new ones in the same row.
Explanation
A buttonhole is usually made by binding off a small number of stitches at the correct spot in the row, then casting on the same number of new stitches over the gap in the same row or the next, creating a small hole sized to fit the button. The exact method varies depending on whether you want a horizontal or vertical buttonhole, and cardigan patterns often specify the exact placement and spacing between buttonholes based on button size. The edge around a buttonhole is often lightly reinforced to withstand repeated wear.

How it is made
The most common buttonhole binds off two to four stitches on one row and casts them on again on the next. A cable cast-on gives the firmest edge and is the standard choice.
For small buttons a single yarn over paired with a decrease is often enough — an eyelet buttonhole, which barely shows.
Placement
Buttonholes are spaced evenly along the button band, but one of them should always sit at bust level. Without it the cardigan gapes exactly where it should not.
Allow five to seven buttonholes on an adult cardigan. Mark the positions before knitting rather than deciding as you go.
Common mistakes
- Spacing buttonholes without one at bust level.
- Buying buttons before the buttonholes are knitted.

Frequently asked questions
How do I space buttonholes evenly?
Five to seven on an adult cardigan, evenly spaced, with one at bust level.
How do I stop the buttonhole coming out too big?
Bind off fewer stitches than you think, and reinforce the edges with a few stitches if it is still roomy. Knit a test buttonhole first.
