I think the reason for only 45 squares of neutral is that later in the quilt where normally there would be neutral 4 patches thrown together, there will be a large piece of neutral in the quilt larger than 3.5 square. I wonder if this one will resemble floor tiles like the last one? It would make the alternating two color neutrals look more like a mosaic. I'm going for 30's fabrics. Odd I know but I had most of the colors. I'm sticking with the lavender and going with blues for the purples and pinks for the constant. My constant will be the white.
