I find that I get "stuck" in my de-cluttering efforts when I don't have a place to put things. I recommend getting something - plastic boxes (using this week's JoAnn's coupons?) or even paper grocery bags - labeling them broadly ("things that cut," "things that measure," "things that mark," "strips," "misc. scraps I can't bear to throw away," etc.) and use them to sort.
I totally agree with others who say, "Don't try to do it all at once" ... unless you get on a roll and want to keep going.
Wishing you a good roll!
