I have made a log cabin quilt piecing it on muslin and my advice is to use the paper another suggested, or go for it without paper. It did make it stiffer, less appealing to snuggle with. How many times will you be "going around the hearth" so to speak? The more times around, the more risk for distortion, but with your width strips, there should be enough fabric for squaring up frequently. Good luck and don't forget to post photos!
