I have used the 12x24 mat a lot. Well, not the one, I've gone through several. I use it for party decorations - -I cut things out pretty big. I also use it when I am cutting out a large number of multiples. One year we cut out tags for our WDW autographs. 3 kids, 10 day trip - -I think I cut out about 150 tags. I made ribbons for swim team time trials - -again around 150 or so. It is useful when I make my Chrsitmas cards too. I used it for Halloween treat bags for the kids classes to.
