Sew the hole and leave a long tail to make the pumpkin sides.
How to make the sides/folds here:
Leaving a long tail, chain 4 stitches. In the second chain from your hook, make a slip stitch. Continue making slit stitches to finish. (You will have 3 slip stitches.) Cut the yarn and pull it through the loop. Once you finish the pumpkin, take both tails of the yarn and use a needle to pull them through the center. You can use a bit of hot glue to keep it from coming off if you want to hold/hang them by the stems. Cut the extra yarn at the bottom of the pumpkin, and you are done!
