Linda, I too have the Mega Mat, and am debating on getting the same thing again. Since I wrote this thread, I have been doing a lot of research. I think I'm going to only get a mat that is 48" in length, so that I can drop one leaf of my large cutting table, and still have the mat on it. Then I can fill in with an added 24" x 36" when I need the entire table top. The added plus of the Mega Mat is the ability to be able to pin into it. I have used that option many times. So, once I get new mats, I will still save a good sized piece of the Mega Mat for that purpose. My current one is pretty scarfed up from rotary cutting tight circles. It now catches on fabric and batting.
And, thanks mailmanldy, for the heads up on the Quilters Select mats!!!!! I didn't know they existed. I love that they have the smaller markings (1/8", 1/2", etc.) all the way across the mat. And, the inch measurement numbers going in both directions! And, all on BOTH sides! I may consider getting two of these to fill the 36" x 48" space. Hopefully, I can get a discount at my Floriani/RNK store. I get most of my Floriani (threads and stabilizers) at a discount there, because I bought my sewing machine there. Hopefully, the mats are included too, since Quilters Select is a Floriani/RNK product.
