I only have a small Olfa mat. Because I've been cutting a lot of strips and have a rotary cutter that's attached to a ruler (very similar to a paper slicer), I've been using my large Fiskars mat forever.
I sat down with the regular rotary cutter and a few templates and pulled out my older smaller Olfa mat....and night and day difference.
:oops: Looks like a large Olfa mat is on the "to buy" list soon...
