GREAT school auction projects here. This was made by a friend with the kindergarten class. The frame was made by her husband over a plain mirror. The ruler lines are adhesive. Check out site for more ideas!
DIY Texas Fingerprint art for my son's preschool class Silent Auction project. Turned out amazing! Progress photos on top. We used a flat canvas. Each child's fingerprint was a different color and we put that on a separate page to give with the painting.
Kid's school auction project - epoxy filled i-spy table. Each child brought in various things to include in the table and they were embedded in epoxy to create a appearance. Could color code objects- like they did at Chloe Clark
