For those who wondered what I was talking about on the strip pieced blanket, here is how I covered the seam allowances on the back.
Take a 2.5" strip and fold in half and press with iron.
Unfold and bring raw edges to the center fold line
Do the same with the other raw edge and press
I laid the strips along the pressed open seam allowances on the back of the blanket and stitched them down. The first ones I stitched with four stitching lines but soon thought that was over kill and the last ones I just stitched with two lines.
