Cut one sock starting at the heel, then straight across.
Stuff sock with pillow stuffing until nearly full, leaving some fabric at the top. More stuffing will create larger pumpkins, so be sure to vary the sizes if making multiples.
Cut about 3 arm's length of twine, then tie the top of the pumpkin closed. Leave most of the rest of the twine to one side of the pumpkin. Trim off the short end.
Wrap the twine around the pumpkin, while pulling the twine tight so it leaves a good indent.
After one wrap, turn the pumpkin 2 more times, and wrap 2 more times until you achieve even wrap spacing, resembling a pumpkin shape.
Wind the twine around the top opening, then up the fabric on top to create stem. Glue the twine to secure.
Snip the fabric across the top of the stem, then glue twine to the very top to fill it in.
Embellish pumpkins with tendrils, faux or real leaves, or whatever you wish!
