Sell it in flat rate box lots if you have lots to sell, much less work involved, I have sold some on ebay that way , just last week
I need to sell LOTS more lol. I am feeling the same way , it is as if I don't like any of the fabrics I have now. I want to just work with the simple solids or batiks and have none of those in my vast hoard of fabrics. In fact I have been thinking about throwing a lot away ! I did send out nine large boxes for postage a couple weeks ago of older prints. I did want to try to sell some of the nicer quality fabrics because I need money lol. But it is hard to sell and very time consuming. Best of luck to you
