I am sorting and filing quilt patterns I have torn from magazines over the last 20 years. I decided that it was time to finally get a handle on all the paper that is just randomly crammed into three ring binders. I knew that there were patterns I would not want anymore, so I got some new pretty binders, some page protectors and 5-tab dividers and commandeered the kitchen table to sort, classify and purge so I can have an idea file that is actually usable.
As I sort, occasionally I come across a pattern and think "Gee, that's nice - I should make that soon" -- and then, "Oh, yeah, I DID make that."
Well, there's 50 quilts in the house - sometimes you forget!
