I have two pressing boards...a huge one for yardage and a small one for piecing. Well I use the small one on my cutting table. NOT a good idea.
My table is now warped...so much that my cuts came out crooked. Yes, believe me. First I thought it was my ruler but after checking everything it was the table. My fault. Now I plan to modify my ironing table into a medium pressing board so I don't damage my cutting table again.
Live and learn.
