I have a closetmaid cube organizer for my Fat quarters, it lets me separate by colour or theme
peg board attached to the side of a wardrobe with hooks to hang all my rulers on.
A magnetic whiteboard to keep a list of UFO's so I look at it before I decide if I want to start a new one. And I post up the pattern there that I'm working on so it's not lost int he shuffle.
Freezer paper to applique with.
Thats all I can think of off the top of my head.
