I did that for my creative granddaughter a few years ago. She loved it. I included a lot of what you all have already suggested. She found a way to use most of it. On my visits, I would bring her other tidbits I would come across. Then one year I made her a "design board" which was foam board covered in pink flannel and a safe scissor and a bunch of fabric that I cut into small pieces and left some larger pieces. She also loved that. And her first lesson was "don't use these scissors on paper!"
