I haven't had it but about 8 months and had to wait for a special sale at JoAnns and got 60% off of a big one. Is there any way to get it to flatten back out???
Earlier this year, when it was 107 in the shade, a bunch of us laid our cutting mats out in the sun on concrete or some other hard surface. Mine flattened out quite well--------------until my son in law laid it over a rock------------then I had to flatten it again. Anyway, mine was not badly warped, but the time in the sun sure helped.
