I have a stash because I am a VERY productive charity quilter. I buy fabric that is a bargain or I could not afford to give so much away.
I make children's quilts and quilts for the military. Also our local Hospice. I am given fabric my members of my guild also.
I have a certain amount of space for all quilty things. I like organization and fabric out where I can see it on shelves. It makes me very happy to see it all and know that soon it will be turned into quilts.
