I have a love/hate relationship with the 6x6 pads. I do love the size of the patterns for cardmaking. However, it often takes me a couple of tries to get my layout and pattern mix right. With the 12x12, I have the luxury of trying different things and still being on the same piece of paper. But with the 6x6, there isn't as much room for error. Sometimes what doesn't work for the current card may work for another project, but sometimes it doesn't. Those are the times that make me feel I am wasting money with the 6x6 pads.
Yet, still I keep buying them...
Guess, I, too, am a member of the paperholics club.
