Now lay two blocks face to face and fold back the background fabric to reveal the quarter circles(QC). (This is only for those blocks where the QCs meet and not for the ones that are on opposites corners.)
They should be face to face. Now you could just sew the two blocks together but this step will make sure the QCs will meet where they are supposed to.
I take the time to tack the edge of these two QCs at the ¼” seam allowance. This is so you can be sure they will match as well as possible when you sew the blocks together. I tack instead of pin as I feel it keeps things from moving better than pins do.
Sew all your blocks together this way and then sew them into your bookmark top.
