Via some blog links, I came across Packandfind.com, which lets you build an online inventory of boxes and their contents, attaching digital photos of your items, etc. Obviously this was originally designed for people with storage spaces, but I think it would also work well for anyone with a big fabric stash (or anyone who has to pack some of it away where it’s not easily browsable).
…that’s HOLIDAY. (Don’t the holiday decorations and sales start earlier every year? A few weeks ago there were battling Christmas and Halloween decorations being sold at a local store.) The Sew Mama Sew blog is doing daily project posts during November, if you are starting to think about homemade holiday gifts.
