I would scan them and file them into the computer with notes. You can put them into an album such as. Log Cabin patterns, baby quilts, wedding rings, Susie's Christmas, Benjamin's Bar Mitzvah, Mug rugs, table runners, Jamie's christening. If anyone asks for a pattern, you might have and as AUQuilter suggested can pay it forward. I would include ALL notes, that way is something doesn't turn out right no one can say you didn't put a step in. Like some people when they pass down a recipe but leave an ingredient or step out so it "Just doesn't taste like you made it". That is just mean. Every pattern I have is in my computer and on a jump drive (also know by other names) I carry with me. I have the paper pattern to work off and follow also.
