I buy 100% cotton scrubs at thrift shops and cut them up for fabric. Every other week our Goodwills have a 50% off everything sale, so I can get scrubs for about $1.50 each. I get at least a half a yard or more of fabric and I find patterns that I don't see in the LQS. Also, because they are used, they have already been washed to death so no shrinking. I even made a nurse friend of mine a quilt made of scrubs. She loved it!! I say use what you've got--and think outside the box!
