I am working on a Snowball quilt and a few of the fabrics are very “strong”. By strong, I mean fabrics that really stand out and your eye seems to go to those designs. When I am laying out blocks for one of these quilts, I take a lot of photos with my phone along the way. The pics will point out where I need to move around those blocks that jump out. Try taking pics of your lay out along the way and see if it helps you balance your quilt!
