Do you know what my favorite organizing principle is? (No, not "the pile", although if you've seen my office, that's an excellent guess.) My favorite organizing principle is "random".
"RANDOM is not an organizing principle!" I hear you saying. Well, just because something isn't a GOOD example of a category doesn't mean it doesn't belong to that category. (For instance, 'vomit' , it's just not a good one.)
Things are nice and tidy and predictable when they're in categories and folders (and, yes, piles) but I like to choose things arbitrarily. Pick the fourth restaurant on the list and eat there. Opt for the book with the most colors on the cover. Talk to the person carrying the largest bag.
Or, my favorite, choose a random four-digit number and search the eBay vintage pattern category using it. That's how I found this gem, McCalls 3053, and I love it! If this were my size, I'd have bought it already — but it's B32. (Sigh.)
I just love the little button and the tuck that defines the sleeve. I'd probably put a different skirt on it, I don't like a center-front skirt seam, but hey, that's just me. Maybe I'll pick the skirt randomly, and see what happens …
