NICE QUILT!!!
I definitely "mix" my fabric sources too. I use everything from WalMart to Joann Fabrics to LQS as well as on-line sources. When I want something really specific I know I can get it at my LQS; they've orders special things for me on several occassions, and I support them as far as my budget will allow. When I need service or am shopping for a machine, I will ALWAYS take my business there!
