I haven't given any measurements for the lengths of the diamond border strips because that depends on the quilt size, but it is obviously quite important to have the strip exactly the right length to give a neat corner. The length of the diamond border can be adjusted to fit either by changing the size of the squares and triangles or by varying the width of the fabric strips either side of the diamond strip.
I'm so pleased that I managed the diamond quilt border without any inset triangles that I now feel that I can consider using it within a quilt as sashing or a frame or something.
Thanks for visiting my blog. Hope to see you again soon.
