This site has several different bag patterns that you can purchase. From the description it sounds like you print the pattern off on your computer but you might want to send her a question & see if it is an actual paper pattern or if she is just talking about instructions. Here's what she says: "NOTE: Print pattern at 100% size, do not resize, scale or shrink to fit."
