Have a garage sale in the spring. We farm in Oklahoma so I will be in that area in May. I'm sure I could use more in my sewing room.
I had a similar problem a few years ago. I took everything out and got big boxes and storage containers. Put all my quilting fabric by color in several boxes. My skirt fabric in another container and if I decided I wouldn't ever make it, that went into garage sale. I sold a lot in one day and gave the rest to a retirement center for crafts.
