After joining the rows, I find that this section is still too narrow for the backing. Rather than add more of the children's towels sideways, I decided to use yukata fabric for the outside edges. I have a lovely floral but it is on dark blue and I think the bamboo on white looks a bit better.
With no place to spread out and arrange the borders, I spread a tarp on the street outside my house so I could figure out a plan. The tarp was too narrow so the yukata fabric is on the street. A light spring breeze kept turning the corners and before I was finished I had to fold it over several times to allow bikes to pass. The section of road behind the camera is only the size of the green tarp, about two meters. For that reason, at least, I did not have to deal with cars.
After looking at the size of the backing, it appears the towel section is too long by about half the width of a row of tenugui. Rather than trim the lower row of children, I decided to remove the second row from the bottom since those children are a bit larger in size. Then I re-positioned the bottom row and added the bamboo to the lower edge as well as the sides. I will not feel as bad about cutting off part of the bamboo as I would spoiling the children in play.
The thing is, now that I sit and look at this picture, I recall the yukata fabric I used for the border of the kaleidoscope quilt (a kind of braided link design) that is just about the width that I need and I bet I have just enough already cut too. Then, again, that might be just a bit too strong a pattern. Un-sewing and re-sewing seams of several meters takes a lot longer by hand so I want to be sure before I go that far. This is the time I really wish for a very large empty room.
