Now that I have several blocks completed, it it easier to see how the spiderwebs form. Again, just laid out on my dining room floor, not sewn together yet. When I do start sewing the blocks together, I'm thinking of pressing the seams open. I usually press to one side. For one thing, it makes matching seams so much easier when the pieces nest against each other. But in this case, I think pressing the seams open will lessen the bulk in the center, where eight pieces come together. Any advice?
