This simple trick will greatly improve the finished look of your knitted projects.
Look at the stair-step effect of a regular bind off in the first photo, compared to the bias bind-off in the second photo.
Use bias bind off whenever you have bind offs over multiple rows e.g., necklines and shoulder shaping.
Pull the first st over the second st and off the rt needle (the standard bind off technique). That’s your first bind off. Now continue binding off normally (k or p a st, then pull the 1st st on rt needle over 2nd and off needle) counting that first slipped st bind off as your first bound off st.
For instance, if you are working st st and you have these directions in front of you: BO 5 sts at beg of next 3 RS rows (beginning with a RS row). It will look like this:
|Row 1:||Bind off 5 sts normally, knit across remaining sts.|
|Row 2:||Purl across to last st and slip it unworked. Turn work.|
|Row 3:||Slip the first two sts, pull the first st over the second st (one st bound off). Now bind off an additional 4 sts normally and k remaining sts.|
|Row 4:||Purl to last st and slip it unworked. Turn work.|
|Row 5:||Slip 2 sts, pull first st over second (one st bound off). Now bind off an additional 4 sts normally and k remaining sts.|
