Hey crafters, cutting mat? (Necro post)

RiotDemon thought this was worth mentioning said

I’m looking at getting a cutting mat for a rotary cutter or a small craft knife for paper crafts.

I have a 50% off coupon at Michaels so I was looking at the Olfa mats. They say they are specifically for rotary cutters and can be ruined with a fixed blade. I guess I could find a tiny rotary cutter to use with paper?

Just looking for some guidance. Trying to see if the Olfa mat is worth the price. I had my eye on the 24x36 size, but maybe the 18x24.
