I love seeing how everyone's units are coming together! Macybaby your string pieces look great.
Here are my half-baked Week 6 units. I did the string piecing using old phone book pages for the foundation.The foundation didn't really work for me, as I had to trim the units again after removing the foundation paper but before adding the corner units. When I forgot this step, I ended up re-sewing some of the seams because the units were too big.
I also tried to sew the bonus triangles when using the sew and flip square method for the corners. This was why Bonnie suggested no seams within an inch of the edge: my bonus triangles often ended up with a a messy seam allowance due to intersecting seams. I decided it was not with the effort to get some half-square triangles that measure 1.25" un-finished.
What do we expect for Week 7? Another clue or another clue and the reveal?
