Tomara: I am new at this too...if you look back to pg. 46, Judy's first picture shows the 2" squares with a line drawn. You place this sq. on top of the rectangle and sew maybe one or two threads from the line so when pressed it works better than following exactly on the line, then repeat for the dark 2" sq. the same way at the other end of the rectangle. Then repeat going in the other direction for the other 24 pieces (mirror image). Hope it is clear looking at the pictures is how I muddle through.
