stay organized. I can't tell you how many boxes I've gone through this year, trying to keep my card stash contained. I felt 'organized' for about 2 months and then I'd go on a manhunt again for a better system. Finally I found an unfinished wood photo box at Michaels (for 4x6 photos - duh - perfect) and added a piece of chipboard for a divider between the 3x4 cards. I love that every Project Life card I have is in this single box.
