lol... when I reorganized my sew room, I went from 4 - 28" wide bookcases of stash to 3 - 24"wide pantries (Pantries are deeper, so I can still put two stacks of fabrics side by side on a shelf).
So I went through my stash of dress fabrics, quilting fabrics and home dec fabrics.. and culled out stuff. I took SIX huge rubbermaid tubs of fabric to the local quilters charity group. Laid it all out, and told folks to take what they wanted... for themselves or for making things for charity. SIX huge tubs. THEN I gave the tubs away!
<sigh> I thought I'd have space. well... what I ended up with is 3 pantries STUFFED full with fabrics and two HUGE tubs of MORE fabric hidden under my table. And a couple of large shopping bags full that someone just gave me, and 6 stacks of fabrics of WIPs, and.... <sigh> lol!
