The hoard is organized! My in-use DMC collection is wound on bobbins and lives very tidily and compactly in four floss boxes (variegated, Color Variations, and Coloris have their own box). Here's how I'm storing my stash of extra full skeins: divided by number and tucked in a baggie with an index card with all the numbers listed on it. Fits in a small box and doesn't take up much space, and so easy to quickly find what I need.
Between this and my toilet paper hoard, I think I'm all set. (By the way, I have been an enthusiastic TP hoarder for many, many years, which is a long standing joke in my family. But when the shortages struck last year, who was laughing then? Mmm hm.)
