I' did flower pots with handprints & a poem, with petunia's in them. This year we will be making colorful pasta necklaces and paper flower's. I've done so many handprints/footprints & I just did the photo shoot for Easter, but could easily work for Mom, using white paper with a M O M, kid holding it up and making a photo collage. I bought the colorful frames from IKEA, so they were stylish, and cheap =)
Good luck!
