Yes, anyone could cut their fabrics into these jelly rolls, but, here's what I really like about them. If you really like a line of fabric and want to do something w/the whole run of the line, it could be very costly and by buying the jelly rolls, it isn't. Not that jelly rolls are cheap...around $30...but, it is the whole line of that fabric. Many books and patterns out there to use and makes putting a quilt together quick and fun:)Plus showing off the fabric line. Also,there are charms, jelly cakes, layered cakes, etc. All of these refer to a certain size. Again,is the whole line of fabric. Hope that helps..skeat
