I bought a mat a while back and it had triangular chunk come out after 2-3 uses! They sent me a new one. Another smelled so bad I couldn't take it! Now I smell before I buy. :lol:
I'm so glad for the color tip. Mine is now an awful yellow on one side and pink on the other-- :shock: but I've been using the same blade for an incredible amount of time--a year? That's never happened before.
I saved on old one for cutting batting for ragged flannels--they seem to wreck a mat.
