The day I bought this play mat I thought it would get a lot of use, but it was not a big hit. The edges curled a lot from being rolled up tightly so it was quite annoying to the boys that it wouldn’t lie flat. We spent most of the time trying to anchor the mat down. It sat in the garage for the last six months. Yesterday I pulled it out again to see if they had any more interest. I walked in the house, and the boys were quiet for quite a bit. I walked back out, and they had anchored the four corners of the mat (that finally laid flat) with stones and were making up stories about the town. They played on their mat for a long time. I walked away for a while again, and when I came back, the mat was half rolled up and tucked back into the garage. Teamwork.
