With Dia de Los Muertos is coming up I thought I'd share this one, even though I would make some changes next time. For one, I would make them thinner and two, I would use larger molds so that we do not have to put magnets on them, they would larger surface area to paint and glue beads and other items on them. However, they were so cheap and a quick project for the students, that I thought maybe you can make the changes as you wish. I saw this mold just now on Amazon and thought it would be good for magnet sugar skulls https://www.amazon.com/Lekue-Crazy-Skull-Game-Mold/dp/B00I5SRLJC/ref=sr_1_4?s=home-garden&ie=UTF8&qid=1507413608&sr=1-4&keywords=skull+molds
1. Using a silicon chocolate candy mold for sugar skulls, I made several skulls of plaster of paris.
2. Students used acrylic paint to decorate them.
3. I hot glued magnets on the back.
