While the thrust of the class was to use your stash, it was mentioned at least once (or maybe I read that into the class) that if you don't love it, let it go. I think the letting it go part, especially after a class where digging into your stash and sort of reacquainting yourself with it, is easier to do, but it's not necessary. I, myself, dug into some of my old, like way old, kits. I'd sorted them out a few years ago (purging should be more frequent) and hadn't touched or thought of them since. As a result, the kids' school was the recipient of a large box of, mostly, patterned paper and cardstock.
First a quick note about my own stash. I don't have specific paper storage, loose paper, that is. I'd say 95% of my stash is in kits (as seen above.) I use them that way, and they stay that way until I've put all that I can to use. Once I'm done with a kit, I'll pull out any remaining embellishments, but the papers are either tossed or put in the donate box. I have some collections of a particular line, but those are treated just like a kit - together until the bitter end. I can tell by my current storage that if I had loose paper, it'd be stored by manufacturer. Cardstock is by color. Embellishment storage is under review - but currently sorted by the type of embellishment with brads, buttons and ribbon also broken down by color.
I'll make these posts short, well after today's, that is. Today, part one:
As you sit with a pile, drawer or stack in front of you, ask yourself, "Do I have to talk myself into it?"
Oftentimes I’ll put something in the “toss” pile, knowing without a doubt that I am not in love with the object or the potential projects it represents. But then I do the double-think thing, telling myself, “Weeeelll, I could paint it yellow/take it apart/learn how to use it…” If you find yourself talking yourself into keeping something, stop. Let it go. Move on. There are plenty of projects and supplies to love without forcing yourself into a half-hearted relationship with Mr. Not-Quite-Right. If you're an altering-it-to-fit kind of crafter you wouldn't be considering that particular item for the toss/giveaway pile.
Look around your space. Toss or give away the first five things you find where you are talking yourself into keeping.
