How about getting some fabric paint in a craft store. Then with adult supervision, paint the kids' palms and make handprints on muslin. You could have them all sewn and let the kids pick out the color. I'd do them really quick, pillowcase or birthing style. Simple X quilting. You're very brave to tackle such I big project.
Edited to say: I see mom6 had the same idea and posted while I was typing. Great idea mom6! LOL
