You may have ordered the exact kind you had but different bolts have difference in dye lots. They say that yarns are the same way. I did like you and ordered the exact same thing I had but it was a blue color. It was off a different bolt I am sure and colors were off. I had finished my quilt and decided to order enough for shams. In my case I didn't make the shams because they would have been obvious, they would have looked faded compared to the quilt.
However in your case, I would mix the blocks up and they would think you planned it that way. Be sure to show us, Purple and gold are LSU colors and maybe a few more, I don't know.Best Wishes-Toogie
