I have all of the shape cutter templates. They are just so quick and handy to use. Only took me just a short time to get the hang of it.
I love that if I'm working on a project I can just pack the cutter and template or two (oh, yeah, don't forget the mat) in a bag. Toss in some paper and just cut away in the lunchroom at work!
Then I can assemble when I get home!
