I had that problem and noticed that because I was using the hard plastic banquet table for my cutting table that is bows in the middle with pressure. Thus making my cuts go crooked. If you use one of these tables try putting a hard board over it.



I was using my kitchen table to cut my fabric maybe the table is just to low

silly question what is waffle-weave shelf cover ?

Good advice memaw4, this is one of the small things but so vitally important that I did learn in a beginners class. I should also point out that it is a money saving tip too.
