I've donated a couple bins of fabric to our church's quilting group (quilts for missionaries), donated some to charity, and tossed scraps. But, I have enough for 14 planned quilts, several bags/totes, table runners & placemats, plus pet-themed projects (guess what everyone receives for gifts from me)! I just bought a 40 yd bolt of W&N that'll be enough for the next 4 years of projects (at $5.75/yd for 90" wide). I have so much W&N now, I can't fit it in my closet yet for easy access in & out. The stash/scraps that remain will be dedicated for scrap projects.
Then, I have supplies for 'scarfs' and beading projects I have yet to begin.
With 20 good years of quilting left, my goal is at least 6 quilts a year and several smaller projects. I suppose I'm disciplined enough to use what I have as long as I don't buy more! Some of my fabrics were purchased at a fundraising quilt fabric sale where fabrics were just $1-2/yard, an estate sale of a former quilter, and a 'down-sizing' sale of another quilter. Those were simply too good to pass up. That's where my 'stash' began. Hoarding or long range planning for keeping the cost of my hobby in check???
