I think the YLF weekly post linked to this post at the CAbi Canary blog: 15 items for 30 days. I liked the idea of it a lot and am thinking about using it as the framework for a month-long challenge using items from my own closet. Anyway, I wrote out all the items and days, in order to start thinking about my possible version:
