I'm somewhat new, so I don't have much. I have a kitchen garbage bag where I toss my strips that my daughter tosses around to choose colors for her quilt. I did buy a small box of old fabric at a junk shop recently. It has some wonderful stuff in it, including two original feed sacks that I can't convince myself to death by cutter yet.
I also cross stitch, no that's a separate issue. I have silk thread coming out my ears from Vikki Clayton. She has beautiful silk floss and perle, ribbon and more if anyone is into crazy quilting. And it is cheap and she is a doll to work with. You can find her at www.hand-dyedfibers.com. Tell her I sent you! She's also got some hand dyed silk duponi that she is selling now.
I'm desperate for more scraps. I'm hoping that I'll be able to come across a stash soon :) I don't have proper rulers or a cutting board either. I am hoping I'll be able to find a cheap one sometime soon.
