Betsy....my Creative Memories cutting system is one of my favorite tools. I use the circles and ovals a lot and even use the large circle quite often. The odd shaped ones like the heart and the triangles I don't use often. Kari has used the triangle recently on a layout and it was really cool! I highly recommend this system. I got part of mine from eBay and some from a dealer. I had to get a bigger mat when I got the big circle...maybe that is all they have now! Anyway...I love it!
