First, I like these. There are a lot of cute designs.
The only issue I have, is that they really aren't for cardstock. A thin paper, foil, tissue, things like that...they cut without any problem.
I used some colored foil I found at the Dollar Tree and cut out nail designs. Really cute. The foil paw prints look so darling!
If you're using medium thick paper, you'll have to press fairly hard. Thick paper (cardstock) doesn't work well). I also found it easier to cut the paper first into managable sizes, instead of one big page.
