All right. I have all the 9- patches ready to sew together, but want clarifification in case I misunderstood the directions. Are the folded squares that make HSTs and tacked with glue onto the white squares, are they supposed to remain folded and then sewn to the other parts of the 9p? In other words, do the colored triangles remain double thickness while the white is single? I didn't see anything about cutting away the other halves.
