If i really like a pattern i have then i take the pattern to the fabric store with me and buy all the material i need to make it then when i get home i put it all in a container and then add that to my stash pile of ** To Do **. That way i got the pattern and the material i need and i make sure that i always buy a bit extra so that i dont run out in the middle of making the pattern. And if just adding to my stash then i like to get min 2 yards of material . And Jelly rolls well i love then so if i see one i like i buy it . I dont buy many fat quarters unless on sale ..
