One method to closing your circle crochet pieces is with the cinch closure.
After you’ve stuffed your piece and fastened off, keep your yarn tail on the tapestry needle. In your last stitches (usually 6 or 12 stitches), weave your needle in and out through the stitches. Once you’ve gone through all the stitches, pull your tail tight until your piece closes! Tie a simple knot right at the base of your piece and weave in your ends.
