I discovered an easy trick to deal with this. Instead of trying to fold your fabric back with a quarter inch "seam" folded into it, while holding it all up to a light or window, to see it the fabric will be big enough, just fold the paper over the fabric! If the paper piece covers the fabric, it's big enough!
