Ooh, we have a winner!
Thanks, everyone, for you all of your good, clever and humorous input! I like the idea of calling the pants "lambies"-- thanks, Melissa! These pants are soft (not itchy!) and snuggly, and I like that it sounds kind of like "jammies" without being too obvious about the wool part. Also, I was trying to think of a name for a line of clothes if I make other things out of recycled wool, and Brother David (and A. Gretchen too, actually!) came up with "Kids in Sheep's Clothing." I love it. So clever.
Amelia and I spent a couple of days in Olympia with the Shacks (including Luke) and on our way out today we stopped at a shop that sells Heather's handiwork and other recycled or repurposed types of gifts. I brought in a pair to show her, and she said she would like to see more, once I make them! That was encouraging!
Thanks again, everybody!
