My primary uses of the Stickies yellow notes are to (1)indicate the category in which papers are to be filed. This allows me to indicate the category and to file later without having to go through each paper again; and (2)tag certain pages of a catalog as I initially look through it indicating which item is of interest. If I plan to shop in-store I take the annotated catalog with me; if I shop online this guides the items to be ordered.
