I tried a faux-cathedral window block from the Youtube tutorial this afternoon. Doing it in blues and if it turns out, I'll send it to my January partner. So far so pretty.
That is one of the reasons why I like this swap so much. It gives me an opportunity to try new patterns and new color waves. I have some plans in reserve and sometimes, doing just one square tells me that I really don't like the pattern well enough for a whole quilt. Or the trial block screams YES! and goes on the UFO list.
