Toilet paper tube, gauze, glue, and googly eyes.
Take an empty toilet paper tube. Help your child to wrap gauze around it, creating layers that overlap in some areas and fold in others. You can either tuck the layers into each other or use a bit of glue to secure ends. Glue on some googly eyes near one end to create a mini-Halloween mummy. You can also use a paper towel tube and cut it into different sizes to make different height mummies.
