Cut yarn leaving a long tail. Using a darning needle go through each stitch remaining on the needle and thread onto the remaining yarn. Once all the stitches are off the needle pull the stitches tight and secure with a knot.
With right sides together sew the side seam together leaving a hole at the top. Do not secure the yarn off yet.
Using a pompom making and the black yarn make a pompom leaving long ends to tie into the pumpkin.
Secure the pompom to the top of the pumpkin covering where you sewed up the hole.
