I've heard from two people who are vendors at Craftsy that some of the shops are being closed. Allie over at Allie--Oops and Deb Kratovil have both sent out messages about this. Allie says she was informed that some of her patterns are going to be pulled and they are shutting down Deb's store all together.
You can read about some of this here.
The point is that if you are like me and have patterns purchased but not saved, you might want to download them NOW. Apparently these changes are going to happen soon.
