Tried using a cheap plastic shower curtain liner as a pattern cutting base in my apartment | Fashion Design Ideas - Freelance Forum - The Community for Independent Professionals
That foam tile trick is actually genius. My old mat did the same thing, it curled up on the edges and made straight cuts impossible. I ended up using a big piece of corrugated plastic sign board for a while, the kind they use for yard signs. It was cheap and stayed flat, but you can't pin into it like you can with foam. Might have to hit the dollar store myself.
