I learned the hard way on the last one of these that I made that I need to stack the long strip so it doesn't get a twist at the end.
Then I turn the stack on its side and pull the beginning from each side and start sewing them together.
I restacked it neatly back and forth and once again pulled the 2 ends around and lined them up and started sewing them together. At the end I clip the fold again. Do this 3 more times and you are done.
I was too tired to press it last night but you can get an idea what it will look like. There were a few places where the dotted spacers lined up with the previous row. When I show the whole top tomorrow you will see where 3 lined up in one spot.
