I would get rid of the material I know I wouldn't use and keep those that I just love. I woul think about the patterns that I would like to make and keep fabric for those quilts. I would also make sure I had enough fabric to make unplanned quilts. Think about how mny more quilts you want to make and make sure you have the fabric for those quilts.
Where do you live? If you wee in my area, I would love to go to your garage sale.
