"I thought these would make great mats for Play-Do, but it tends to stick more than I expected (eg more than it sticks on the table). Also, parents have to make sure kids use the right side, as one side is textured, and Play-Do gets caught in the texture. The texture seems to be to prevent sliding, though the feature doesn't work well on all surfaces. All-in-all, these aren't bad, but I'd probably like them more, despite my other complaints, if they were bigger. Ultimately, they're too small for kids to really keep Play-Do and clay on them."
