I agree with you, Auntpiggylpn! What good is knowing how to quilt and enjoying it if you can't afford to buy fabric.
"Best" really means the "best" you can personally afford and do.
Also, check out thrift stores and places like Good Will or Salvation Army. Sometimes you can pick up very nice fabrics at a low price. If you like flannels and don't mind winter or holiday themes, then buy flannel sheets at the end of winter, when they're on sale.
