Let me just say, I was never interested in these playmats until I saw them at a local grocery store. I bought 2 sets thinking okay I have one set for outside, and one set inside. My daughter(2 and a half yrs old) LOVED the mats so much I ended up buying all that were available at the store and I put them covering her playroom. She has a little brother(5 months old) that will get alot of use out of the mats, he actually has so far. I use them inside and outside. When it's a nice day outside I bring 4 of them outside, cover the mats with an old blanket give her paper and she uses her washable paints and markers. Far away from the house, but not too far that I can't supervise her, it's her own creativity/disaster area. When we are all done outside I wash off the mats(and her), the paint does come off easily and I bring them into the house. SHE LOVES THE MATS. Daddy can rough house w/her on the mats. I feel they are fairly priced for what you can do with them. Unlimited uses, just use some creativity w/them. When it's not hot out I plan on doing a picnic w/them outdoors. It is so much more comfortable then being on the grass.
