I copy all my patterns to stuff called Pattern Ease. This way if I change size I haven't lost the pattern for good. Its strong enough that you can use it numerous times. I got it at JoAnne's and you should be able to find it where they keep their stabilizers and interfacings. I buy it by the bolt as I've used it for other things too. Made my own pattern for cushions to go on my porch swing, etc.
