Someone on the main board posted a link to a new BH pattern "unchained". She used a vintage quilt for inspiration. This looks like a great pattern to use up 2.5" squares. From looking at her instructions, it appears she's going with a smaller size square, so going with candy size would mean making less rows.
I've been so on the fence about joining this year, as my candy stash large enough already. So I'm actively working on pattern that will get them used.
