Loosely chain 31 stitches with yarn and hook.
In the 2nd chain from your hook, make a single crochet. Keep in mind you will be working from right to left. Single crochet in each of the remaining chain stitches. You will have 30 stitches at the end. Chain one stitch, and then turn your work. You will now be woking left to right.
Tie off crocheting
Single crochet into each stitch across, this will give you 30 stitches. Chain stitch at the end and turn your work. Repeat Step 3, 7 times. At the end of your last row, leave a 12" long strand of yarn. Tie off the crocheting, but do not weave in the long strand of yarn.
Sew sides together
Bring the short sides of the cuff together. Starting where you ended, weave your hook through the last stitch. On each end of your cuff, take the long strand of yarn and pull it through the stitches with your hook. Continue until you have the entire side sewn together. Tie it off with a small knot and weave the remaining yarn into the stitches.
Use the threading needle and the embroidery floss to sew the wooden buttons onto the seam you created in Step 4.
Put it on
Put the cuff on by placing it over your foot and pulling it up the legs, over the pants. The cuff should fit snug, as the crocheting will stretch over time. To make the cuff bigger, add 2 chains to the beginning chain, and then wrap the chain around your calf to see if it will fit. Continue adding 2 chains at a time until the size desired is reached. Continue on with the rest of the steps as written.
