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.
When I get to the end I slip my scissors in and cut the fold.
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.
I took another photo of the arrangement on my wall while the sun was coming in the east window. You can see the texture on the mirror frame better as well as the colors in the little art pieces.
