I really don't think this quilt needs anything more. IMHO I would try several fabrics on the light side because the squares stand out so well.
p.s. I love your Maytag!

Needs a frame of some kind, preferably a solid color! That will perfectly set it off!

I think I would just add a black binding. It is busy enough to carry itself.

Boarders just seem to finish the quilt, so I go for a boarder.

I was going to say no borders needed, but as I looked more at your nice blue quilt holder, I decided I like the blue on the side so I changed my mind and say yes, a blue border. LOL

In general, I like borders too, but this quilt is beautiful just as it is. Nice job.

I vote No border.

my vote is no border. looks more modern

I think the quilt is beautiful and lots of work!!!
Pretty as is or if mine, I would like narrow black border with 2 inch red on the outside .

Congratulations!

I think it needs a border. A border will be a place for your eye to stop and return to the quilt.
Without a border your eye justs roams off the quilt and beyond. :)
