Myself, I would add a narrow black strip, narrow color strip and then a wider black. That would really make the center stand out. When adding the narrow color strip, you could even use a different color on each side.

Love it!

Black sounds good to me :o)

I'd stick with the black. Lovely, lovely quilt!

Your carpet looks like the ideal border.Having plain black might be a bit too harsh for the dancing colours but breaking the black up with a small spot would be ideal.In actual fact, the carpet looks like a very dark, steel grey and that is why it looks good - because it doesn't dominate or compete with the centre.

Wow what pattern is this?

Beautiful quilt & I would just use a black border so you don't take away from the blocks.

Your quilt is stunning! Love how you made the squares come alive. They look 3-D. The planning must have been mind boggling. Are your black stripes one inch finished or cut one inch? Is the black plain or a print? I am seriously considering making this to use up my stash. How big is your finished quilt?

IMHO- Cut a narrow border of the stripes, in random order (as in quilt), and put a wider black border on either side of it? Same for binding stripes?

I looked at this and immediately thought - black border with a bright binding
