Other projects you can make are cards embellished with peeps, Spring/Easter assemblages, garland, banners. Line a wooden frame with peeps. What about peeps jewelry? Or how about peeps in a jar. Peeps in a box or peep crowns.
If you can't resist the urge to not eat your peeps for craft purposes, then make your own out of air dry clay such as model magic from Crayola.
