I was a die-hard paper scrapper for years and years before going digital. I had an entire room filled with racks and racks of papers, shelves and drawers of ribbons, flowers, brads, etc (now granted, i did a lot of work for mags & manufacturers, so I didn't pay for most of it)... but still, a TON of stuff.
Then I thought I'd just "try" digi back in 2006.
I kept all my paper stuff for a long time even though I never used it. Then I sold off a lot of it thinking i'd keep the basics for cards and stuff. After a couple of years of that and when I got ready to move, i realized that it was all just collecting dust. So, i got rid of all my paper supplies, and it's SO freeing!
