Greetings everyone!

I watched an episode of America Sews with Sue Hausmann 2 weeks ago episode 2901 to be exact. A lady I believe her name was Joyce Drexler was making piping for something or other but she had a plastic cutting board that the piping laid in and you could cut the excess fabric away leaving an even 1/4 inch seam allowance. I want that board! But, I cannot find it anywhere. Did anyone by any chance watch that episode or know what I'm talking about? I'm making a crazy quilt hobo purse and I would like to put thin piping inbetween some of the cuts but I can't cut straight to save me.
Any help and I would appreciate it! By the way I finished my quilted bed comforter! It didn't turn out half bad for my first one! But I hate to admit I am already bored with it and want to make another one! I changed my mind about liking the colors, pattern etc. Does anyone do that too?
