I love doing the Hope You Can Cling To Challenges (HYCCT). As an extra challenge to myself I try to make as many cards as I can with one collection of papers. With over 30 challenges with HYCCT its a good way to get a big tasty bite out of those paper pads. Once I have got the most use out of a pad I will purge the left overs and make room for something new.
I love 6x6 pads too!
