Feeling sure that there must be some rules for this sort of thing, I googled it. I found a site complete with competitions and registration. It sounded a bit too organised for me and I can't for the life of me find the site again. There are stash busting tips for knitters too.
I wanted to know if backing fabric and boarders count. Can I still buy fabric for making gifts? Then I found this pledge. It sounds like me.
If anyone is keen to join me on the stash busting, let me know. You don't even need to be a quilter, just a crafter with some hoarding habits to break.
Note: I've had the set of catalog drawers for a while but only just finished the labels for each drawer.
