Kids Sewing Kit Ideas

My nieces have taken a liking to their Aunt's hobby (!!!!) and have requested sewing kits for Christmas. I am really excited about putting these together and would love ideas from the O & S community on what else to include. They are almost 5 & 7 and there are no other kids in the house, their mom is okay with some sharp things but asked I use common sense. Ideas So Far... 1. Lots of Fabric Leftovers from past projects/stuff from my stash I haven't found a good use for (and don't think I'll be able to use)...which of course I'll have an excuse to buy more fabric :) 2. Lots of Ribbon 3. Kid Scissors 4. The Dullest/Easiest to Thread Needles I Can Find 5. Embroidery Floss Easier than regular thread for little fingers to get through a needle 6. Pin Cushion for Needles 7. Buttons 8. Stick On Velcro 9. Pattern for Dolly Circle Skirt 10. "Made By Nora" and "Made By Etta" Labels 11. Thimble 12. Home Made Bias Tape 13. Container To Hold It All
