This would make a nice ornament gift bag! Knit up the small ornament, then make the ties for the top. Enclose a gift of money, small toy, or candy, pull to close top. Make lots of these to hang on the tree, or add as a package trim. Put one by each place mat at a Holiday dinner table, and let everyone have a secret treat inside! This uses multiple strands of crochet thread, and US # 5 knitting needles. You could easily use a different thin yarn for the ornament.
