After I finished vacuuming the basement I designed the last 3 blocks. I carried those 3 along with the one from the day before up to the sewing machine on the main level.
Here they are sewn and ready to join the other 14.
I need to move them over to the other design wall where there is better lighting. Then I can rearrange them for a better distribution of the colors. I will also decide at that time whether they all work or if I have to make another one or two.
