The instructions for part 4 of Bonnie Hunter's 2017 mystery "On Ringo Lake" were posted on Friday. Our unit for the week is a square with triangles on two sides--I don't know if there is an official name for these units, but we are making lots of them. I have 40 of them done and many more started. Bonnie used brown and aqua for hers, but my colors are black and red.
As usual, I couldn't resist playing with a combination of parts from all four weeks. I don't imagine this is anywhere close to Bonnie's design, but it's fun to try out some possibilities!
