Welcome to the Quilting Board!
I am not sure what your question is, but I love your quilt :D:D:D
I'd like to see a narrow border of the aqua color placed on the outer edge and then another wider border on the outside. This will bring your eye to the edge and the aqua in the blocks won't seem like that color came out of nowhere.
I think if you put a piano key border with every other one white would make a wonderful autograph quilt. Just a suggestion- I think you have done a wonderful job. Quilting queen
It looks great whatever you choose for the border will only add to it much. A friendship block border wd be great and mimic what's within the quilt besides the signing that could be done. :-D :-D
