I like my rotating mat. Have had it for years it is flat to the table, and square. I think I got it at Joann's paid maybe $25 for it with a coupon.. When trying to just turn a small mat it seemed I always moved the fabric and had to realign everything. I did try one of the new round rotating mats. Did not care for it, seemed set to high off table and had a small lip that got in my way. Way over priced for me.
