How do you store your patterned papers? Do you sort by theme/pattern, color, manufacturer, or some other criteria? If you buy kits, do you keep the kits together or break them up?
Right now I have a lot of kits that only have a few partial papers and some embellishments in them. I'm going through a reorganizational fit just now, so I think I'm going to break them down.
Most of my pattern paper is either a pad or kit. I keep kits together in the plastic bag they arrive in and the pads I stored in an upright position in one of the cubbies in my Ikea bookshelf.
