I just went through ALL of my scrapbooking papers. It was mostly sorted, but it was still hard to find things.
I ended up pulling about 2 inches total of papers out. They were either papers I've had since the start of scrapbooking, hideous, or I have more then 2 copies of that paper.
I then sorted it again. I have a Christmas folder and a Valentine's/love folder. Those are pretty specialized and I work on just that at a time. The pirate pack, fairy pack and church/stain glassed packs stayed in their original wrapping and were put together in a folder. The 3 cardstock specialty paper packs stayed together. Then I put all the solid 12x12 in a folder. Finally I sorted all the rest of the papers by color. Red, pink, orange/yellow and browns went into one folder, separated by color group. Blue, green, purple, black/white went into another.
This is the second time I've done this and I'm now down to one milk crate of papers and there is PLENTY of movability space to find things (a little less then half is empty). I can find things, am not overwhelmed by a sea of papers that are nice, but I've never managed to use and I have a refined system to use.
Now to finish sorting the scraps, then the stickers and all the other random bits that got delegated to my desk and I can start card making again. This is actually getting me excited to do so again. I guess there really is such thing as too much of a good thing. It was bogging me down.
