I can go no further until I do the embroidery on the remaining three corners and piece the seminole strips but it’s now possible to see how I can sew all these elements of the quilt together – attach elements, but then open the edges so I can sew the next piece then resew the end of the seam – in other words: partial seams. I now know what the measurements for these corner segments are as well since I’ve been able to fit in the first of the eight which fit between the on-point border and the corner square.
So now, back to embroidery and seminole piecing!
