I know how you feel dotty. My favorite was the hancock fabrics that just went down forever closing the doors. I tried to buy as much as I could use from them to keep a small stash around to sew with. Hopefully you can do that too.
I guess we will have to watch the on line sales to find what we want or need. I do sometimes buy from connecting threads who will ship free if I buy over fifty dollars worth. It is pretty easy to do since I like to buy my batting there on sale.
Many other sites have sales at different times of the year. Craftsy comes to mind of three purchases I made that were fifty percent off what I needed. The fat quarter shop on line has many nice fabrics in their clearance I have bought and been happy with.
