They were fun to make, and not difficult to do.
I have recently discovered Craft Stamper and wish I had found it a long time ago as its a brilliant magazine.
I was getting very bored with my regular craft mag. which was mostly cards and just seems to be sticking to the same old formats with newer papers. Igot really disillusioned with them when they did a short "interview" with Tim Holtz and obviously asked one of their team to design some cards using his products. She was definately not a fan as her cards were as dull as ditchwater.
