Using freezer paper means that it must be removed at some point. I am stitching down one side of the 'petals' in the center of the block then removing the paper just prior to stitching the second side down. I took them out of the outer edge petals on the first block after stitching down the one side but soon discovered that they should be left in until after the blocks are joined as the outer edges have not stayed turned under. I was trying to make the block look nice to photograph and when I hit it with the iron, all those edges kinda got messed up. As a result of this lesson, the block on the left may not make the final cut unless I am able to do needle-turn on those edges. That will be determined when we get the block joining instructions.
