I saw this idea on Moda Bake Shop last year and Jemma finally made them with me this year. All you need is 10″ squares of fabric, 6″ length of ribbon, rick rack, or trim, toilet paper roll, and glue.
Roll the fabric around the toilet paper tube, use glue when you start and then a little at the end. Tie the ribbon or trim on each end of the roll in a knot. Voila, firecrackers.
