Thanks! I didn't buy them yet, so I'm open to suggestions.
Other ideas I had for the 10 year old is: adult coloring books instead of the spirograph or a Claires 20 piece earring stud set. It's about $20.
I have both a 6yr old & Tweens. I think all of it is fine but my girls definitely would like adult coloring books & earrings over the duct tape kit. We've had those kits and it wasn't s big hit. They'd like the Spirograph and jewelry bead kit a lot.
