I'm working hard now: both on the piecing of these circles and on my quilting. Today I pieced another run of squares for the top, bottom and left hand side, so just the right side to go. I'm pretty sure that will be it.
Having said which, I laid it out with a little gap between the existing section and the new bits, so that you could see what I was adding and I kind of like that little gap. Now I'm wondering about finding a fabric to add in there to retain in. This may be too much fiddling about for me - depends entirely when I do it - or may not look that great when I come back to it, but I am pondering.
Need to make that last strip first though.
