This is what my quilt will look like. It was so exciting to finally start putting pieces on the wall! I'm thrilled with it, even though I don't love the effect the heavier gold has on the pattern. I think the on-point black grid will still be obvious. I was going to make the 4-patch centers, to compare with these, but these seem to have good movement, so I think I will just proceed as is.
My shoulders slumped every time I thought of doing the full size, so my plan is to go with the 4x4. My sewing room is very small, so it was hard to get far enough away to get all of the blocks in the photo. Bottom photo shows the backing fabric I bought, which I'm not totally loving compared to others I've seen. I'm thinking I will piece something simple to bring in some pink and gold, so the effect isn't so overwhelmingly blue-green-y.
