I have to constantly fight the urge to hoard. My husband might think I lose this fight more often than not, but well, he's just not seeing the big picture!
Saving all of the sheets of paper from our easel is one the hoarding compulsions that I cannot conquer. However, I just killed 2 birds with 1 stone: keep the nostalgic paint smears AND SAVE MONEY ON WRAPPING PAPER!
Granted, the paper that came with our easel (similar to the one pictured, but cheaper. Ours is from IKEA) tears really easily, so wrapping oddly shaped items isn't ideal. For books, boxes and well, anything for grandparents... this paper is PERFECT!
In fact, a certain father-in-law of mine has been known to re-save the wrapping paper... and the HOARDING CONTINUES :)
