I am looking for creative class gift ideas for older kids - 4th and 5th graders - to do for our annual auction. We typically have done quilts, small tables, last year we did a small blanket chest. Any fresh thoughts would be most appreciated!

When we had our auction in the spring each class did a project that we auctioned off. They were our best sellers. The kindergarten class did handprints and their names on white linen placemats and a table runner. The first grade painted a child's rocker bought at a flea market white and put their handprints and names on it. They also wrote a story about the rocker as a class and wrote it by hand and illustrated it. Our preschool class had a handy grandpa who make wooden garden benches and they put their handprints on them. The second grade put handprints on family sweatshirts (childs, M and XL). Other ideas included quilts, cookbooks, handpainted desks and an granny square aphgan with squares done by the students taught by a crafty grandma. Hope this helps.

I am looking for ideas for a project that could created by a class of 26 kindergarteners for our spring auction.
I had an idea of each child making a fingerprint picture but not sure then what to do with them.
Any creative people out there with ideas for this or another project?
