A block a day is too much of a commitment for me. I'm doing Pat Sloan's solstice sew along. It's a block a week till the middle of the year. I'm also doing the Meadow Mist mystery. Clues are once a month. I'm committed to using my stash and the BH mystery and other sew alongs have been a great incentive. I have two rules when deciding which ones to join.
1. All fabric must come from my stash (backings excepted)
2. It needs to fit my schedule and allow time to work on UFOs
We'll see how this works out in 2017.
