Thrift shop?? That means somebody will sell your fabric and make money off of your fabric. I think when the time comes for me, I will donate my stuff first to family members. Sisters (I have 6), neices, any of the cousins. Then to a church sewing group. The one I used to go to has a group that sews for donations to various organizations. Or to other quilters, guilds and the like. Or you could have a quilting garage sale?? Advertise in the paper.
