If I had to pick a favorite material for toddlers, it would probably be fabric. This canvas held up to tempera, liquid watercolor, sponging, washing, paint stick scrawling, and more. I loved seeing these transform week to week in Friday Mini Makers, our class for ages 17 months-2.5 yrs. We still have 3 weeks left, but next session starts the week of Sept 20!
