Grann, I'm with you. I also lived my whole life "save that, don't throw that away, etc." Result: my basement could have been shown on Hoarders> Since DH lost his job we've been down-sizing--I've taken at least 4 SUV loads to the Humane Society Thrift Shop.
As for fabric, I save my salvedges for another quilter but anything I have to ask "is this too small?" out it goes. Life is too short to worry about (literally) the small stuff.
