These are very nice stencils that you can use with the Curvy Cutter. However, I wish that the circle ones you could make a little smaller circles, because the smallest is pretty big. It's a nice product though. Sturdy!
I asked for this as a birthday gift (some people ask for clothes or jewelry, I ask for scrapping supplies!) My first experiments have been a bit mixed. This came in a bundle pack with the cutter, but no clear instructions. Trial-and-error have taught me more about how to use, but I just stumbled onto the adjustable arm for the cutter - too late to do the super skinny circle I wanted, but that's OK. Warning: Test this out on lots of scrap paper before you try to make a circle you'll use on a LO! It took me lots of torn circles before I got clean results. Still, I want a glass cutting board - and maybe the othe circle templates; this one is quite limited in sizing.
Linking these together and taking them apart is slightly difficult but no too bad. I don't have the other templates so I don't know how this compares. With this one I have had some problems with the paper tearing or getting slightly crooked circles which is frustrating. I realized that you have to push a little toward the outside of the track to cut where i should.
