When a pattern says to "BO in pattern" what exactly does it mean? Many knitters are interpreting "bind off in pattern" to mean that you work the stitches as they appear. This creates an odd looking last row especially in patterns like Seed stitch.
If a pattern tells you to "bind off in pattern", it's telling you to essentially work the bind off row in the same manner as you would work the next row in the pattern. If you're working the below chart and you've just finished Round 2, and the pattern tells you to BO all sts in pattern, you'll actually work Round 1 again during the bind off. If you forget for a moment that you're binding off, just work the next round or row in sequence, that you would normally work if you weren't binding off. The only difference is that after you work one stitch, you're lifting the first stitch over the second and off the needle so that one stitch is bound off.
