Fun for kids: DIY Fort Building Kit. Cool gift for a child. Includes 2 sheets, rope, flashlight & batteries, suction cups & clothes pins(for ties sewn onto corners of the sheets), & simple storage bag.
Recycled jeans notebook or planner. Use a regular notebook, and cut up them jeans that the kids have outgrown. Also a good idea: using a larger notebook and a patch/screenprint from an old favorite shirt.
