My next step was to separate into color groups and sew 5 strips of each color together. Once I had all the strips sewn together, I went with 10" to cut the strips into blocks. Why 10"? I wanted larger blocks and then that seemed like the least amount of waste in a 42" strip.
I cut out several 2-1/2" white squares and drew a diagonal line in the square (corner to corner). The squares were attached in all 4 corners of the 10" strip block. I pinned in place, stitched down the line, cut off the excess, turned an pressed. This was down for all the blocks.
I laid the blocks out on the floor and decided to go with a diagonal color placement. I am quite pleased with the new lap quilt. This would be perfect using one jelly roll and making a baby quilt.
