As soon as I got this, I broke it out of the package and tested it on some junk mail typing weight paper. It worked beautifully. I next tried it on some cardstock weight papers and again had great results. The circle is indeed the 2" described at the largest point but the casing of the punch is considerably larger than I was expecting. Finding proper storage for this will be a concern. I intend to use it for making gifts tags for one thing but am sure it will have many other uses for cards and scrapbooking.
These are so hip, so cool. so pretty. It all depends on what you want to do with them. Plain cardstock, patterned paper, a photo, a stamp, journalling, layering, inking, painting, etc, etc. I love the ease that they cut with too. If you turn them over you can see precisely where you want to punch on say a picture or something. I love to stack/nest them too. These are the most versatile tool ever.
I just received my scalloped circle punch. I've wanted one for a long time and finally I have it :D It fits perfectly with the Fiskars - Large - squeeze punch I ordered with it. I can't wait to start doing my Christmas cards, I'm going to have so much fun!
