Here's a possible quilting pattern to use with the snowball blocks. Each straight line of quilting is parallel to the diamond shape formed by the 4 triangles, but not in the ditch. How far off from the diamonds depends on the size of the snowball block and the corner diamonds. I think that 1/4" off from the diamonds would work for the "man" quilts. The numbers along the sides represent the order in which quilt lines.

As a bonus the other drawing is the possible layout for the "tiled" backsplash I want to create in the kitchen if I ever find the 1/4" tape.
