I made a permanent pattern to use over and over with a few changes for a knit top from a rtw one that I liked and wore out. The first one I cut I was amazed at how much faster I could cut them out since I did not have to fiddle with folding the fabric evenly. Also on larger sizes you have to be sure not to fold too much out or you will not get the front and back out of the width. I think from now on I will make a full size pattern for anything I will repeat from knits or fabric that slides about. For someone using a basic pattern for children or adults that will be made repeatedly such as jammies or tees, give it a try. You won't be fighting with wide big pieces of fabric any longer to cut out your pieces.
