If desired, you can crochet a border on your wristers, with or without incorporating additional beads into the design. Use a crochet hook that is close to the size of the knitting needle you used to make the wristers.
Attaching the Yarn
With RS facing, join the yarn to the knitting at one corner, ready to work across one of the selvedge edges. Insert a crochet hook into a stitch on the edge of the piece and draw a loop through to the front. Wrap the yarn around the hook and draw a second loop through the first to secure.
Attach the yarn as for other crochet trims. *Slide 5–9 beads (or however many you want!) up to the join, then work a single crochet. Pull the loop very large and draw the whole ball of yarn through it as if you’re fastening off. Repeat from * all the way around. After the last stitch, cut the yarn and pull the tail through instead of the ball, to actually fasten off.
Crochet Shells
To be exact in your numbers, you’ll need a multiple of 6 stitches plus 1. For example: 36 + 1 = 37 or 18 + 1 = 19. But since we are crocheting into the edge of a knit piece, you can fudge on the last couple of shells to make them fit.
Join the yarn to the knitting (this counts as the first single crochet).
*Skip 2 sts, work 5 double crochets into next st, skip next 2 sts, single crochet into next st, rep from * to end.
Slip st to first single crochet to join and fasten off.
Single Crochet with Crab Stitch
Single Crochet is worked from right to left. Insert the crochet hook into the next stitch on the edge of the piece. Pull the working yarn through to the front. Two loops are now on the hook. Pull the working yarn through both loops on the hook. One loop remains on the hook. Repeat until you have worked across the entire edge.
Crab stitch is worked from left to right with an extra twist in the yarn to make it have a texture instead of being just backwards single-crochet.
