All you will need for this crochet sock monkey eye patch project is a skein each of red, white and beige-and-white striped yarns in corresponding weights, plus the appropriately sized crochet hook, two flat black buttons, needle and thread. You can use an actual sock monkey for reference or pictures of sock monkeys, to make sure you are staying true to the look for your eye patch. To create this eye patch, you will need to understand basic crochet stitches, both straight and in the round.
To begin make a slip knot with the red yarn and slide it over the end of your crochet hook. Chain 6 stitches. Turn the work and slide your hook into the second chain from the yarn loop on your crochet hook. Create single crochet in every stitch through the end. Turn the work and chain up one more stitch. Single crochet back across the row. Fasten off the red yarn. You have now created the mouth of the sock monkey.
Make a slip knot with your white yarn, slide your hook through any stitch on the red piece you just made, then put the slip knot over the hook and pull it through. Chain to attach the white yarn to the red. Crochet around the red piece with your white yarn for 3 rows, making an increase every 4-5 stitches. Fasten off.
Repeat the attachment process with the beige striped yarn. Crochet around 5-6 rows, again increasing every 4-5 stitches. Fasten off. Cut pieces of beige yarn and tie them to either side of the sock monkey face as ties for the eye patch. Sew the black buttons on for eyes.
