Oh, that's easy! You'll need some yarn, knitting needles, and a pattern to follow. Start by casting on the required number of stitches based on the pattern. Then, follow the pattern to create the shape of the stocking, using increases and decreases to make the heel, toe, and ankle. Finally, bind off the stitches and weave in the ends to finish the stocking. And there you have it! A beautiful, handmade Christmas stocking.
