I have been drooling over the 90 piece FQ set for ever!!! Everytime Craftsy has it on sale, I send the link to my other half but I haven't gotten it yet. . . I made a biscuit quilt out of Fossil Fern charm packs and those did have a number listing stuck in with the charms. My guess is that the number corresponded with how they were placed in the package but I'm not sure.
