I think you are right, it looks like I just added a slab to make it bigger. It is the Star Crazy quilt and I completed just like the pattern, then added the 10 " of the white to the last small green border.
I do think your suggestion of using a light color instead of the white would look better than that white on white. It would look more finished. I was hoping not to have to deal with those long borders again, but guess I must since I am so unsure at this point. It has been too much of my time, and work to get it quilted before I am completely happy with the look!
Thanks Janet
