Love your mind set....when my mother and father died and I cleaned out their house, I had a horrorable time getting rid of stuff. Of course I saved ALL her fabric. Four house/city moves latter I really started looking at those boxes, and went thru them, I was still working full time and had not gotten 'that deep' into my quilting. I had 30 boxes of avacado green, orange, lime green etc fabric that I knew I would never ever use or want to use....found a local group of older ladies that made charity quilts and donated them all....Had 6 boxes of quilting magazines, went to local quilt shop to pass on......after I was all done I felt so good, those items no longer owned me....I knew where my mother was and she was not in those boxes.....
About once a year I like to go thru my entire sewing studio top to bottom end to end and weed out my 'stuff', will I ever make the expensive pattern, probably not (sell it on ebay) did I get every thing I wanted from these magazines (go to local quilt store) and finally my fabric...a stack to be made into charity quilts or charity pillowcase...and a stack to Goodwill/Salvation Army for someone to find and use up.....
After all have to make room for new fabric.....
