Part one, in the photo below, used the pink-green-pink unit, with brown triangles added at each end. I do have an idea of how these will be used, but I'm not sharing because we were asked not to!

Part #2 of clue #6 instructed us to sew 5 of the half-square triangles together in a row, like this:

This is going to make a huge quilt, at least queen size. When I see how all the pieces fit together, I'll decide how big to make it and what adjustments are needed.
Can't wait until Friday morning when clue #7 is due!
