Here we go: On page 38, at the top of the middle column, is a description to make two Unit 4's and one Unit 5, using the orange E, F, H pieces and the gray G piece. My confusion is that when I sew F and G together, the completed piece is 6" long. This completed piece must be sewn between pieces E and H which are each 5 1/2 inches long. There's a 1/2 inch discrepancy. The block picture seems to show that the combined F and G piece is the same length as E and H but it's not. Unless I'm doing something wrong. I was wondering if F should have started at 5" and not 5 1/2". Is this an error in the instructions? I believe I should sew the F/G piece to E and H and not cut off any of the G piece at the bottom but rather cut off 1/2" of the orange end. Your thoughts?
