I just bought a new large matt. Its the green one, Olaf. I got a 50% coupon at JoAnn and then went on Senior day so I got an extra 20% BESIDES. The self healing are the best. Once a year I soak it in the bathtub and it revives it quite a bit. I cut uo the warped one(ironing mistake) and use the pieces for stabelizers in the bottom of swimming bags etc.
