There are lots and lots of blogs out there with fun things to make- maybe you could do a search for crafts of things she really likes and print out some ideas and the supplies to make those specific crafts as well as a few extras. There are lots of craft kits at the craft stores, but I think they tend to be expensive for what they include. When I was 5-6 my personal favorite gift was a whole bucket of beads and string to make my own necklaces. If she's into jewelery making, there are lots of cute beads out there!
