The first two quilts were made by Sarah and Jennifer who trimmed the ends as recommended by the instructions. You'll see that the end blocks are not the same size and the inner blocks. Sarah added a scrappy sashing which kind of reduce the effect of the trimming.
Carol took her quilt top apart and decreased the size of the blocks by 1/4" and resewed back together. That made for less trimming on the sides, not loosing the symmetry of the quilt blocks.
LeeEtta and Sue decided not to match the blocks at the seams as suggested by the instructions. This made for less trimming on the sides as well.
Cherie and Sharon decided to make their quilts vertical and in doing so made more units to prevent trimming the blocks. This gives the quilt a make over, especially for Sharon's who's quilt is the larges size of all those shown.
