I have bought one bundle of FQ. The fabrics are beautiful. The price was good compared to what I can buy locally.
Also being in Canada the shipping was reasonable.
I have thought about buying batting, but do not have a current project that needs it.
I did buy a bundle of two sizes of Wonder Clips. I also bought some knock off ones from Amazon to compare. There are minor differences between them I will see how they hold up. If the Amazon ones work as well I will buy them next time at 1/2 the price and faster shipping.
I have also bought from Craftsy. Happy customer there too.
