Check out Missouri Star. You can check all the jelly rolls to see if there are doubles. Click a JR & you get to a page with a description & a pic to click on to show how many fabrics there are. Free Spirit & Riley Blake will have 2-3 of each print. Moda will depend on the designer. Somerset says some duplicates but the pic of the fabric shows 40 pc. so with a 42 strip roll there will be 2 doubles. I have been disappointed on other sites with doubles/triples so now I try to remember to check.
