there is a difference between (designer fabrics) and licensed fabrics...
licensed fabrics (like disney, nfl, college fabrics) you have to get permission to use for anything you want to sell-
pretty much all of the fabrics we buy for quilting are (designer fabrics) can be used- and it is nice to give the fabric designer credit when a recognizable amount is used---you can not call your item a (jenny beyer tote) unless it is---but you can say made with jenny beyer fabrics-it is the design that is copyright protected- which is why you can not say it is a jenny beyer tote- unless it is one of the totes she designed---then you would need her permission to sell it....that is using a design.
