1. My ATG
2. Adhesive eraser because no matter what adhesive I use, I'm fully capable of making a mess.
3. Border punches. I use one in some way on most of my pages, often in strips for embellishments or framing.
I also would hate to be without my wide-format printer, cuttlebug & cameo or cricut.
I have several favorites in papers, but I seem to like most all of Donna Salazar's.
