The color that jumps out to me when I look at the quilt is blue. Maybe squint and see what color jumps at you and that would be the color for the border.

Maybe blue and black. Blue on the outsides of the border with an inch or so of black in between the blue. Does that make sense?

Oh wow, what a great quilt.

so pretty! When I first glance at it I see what looks like bright pink, like hot pink, stand out. Maybe that would be a pretty border color?

I guess I'm different; but I would just put white or muslin binding all around it to make it look more vintage.

I love your quilt! As a leaders/enders project, it's easy to accumulate that many pairs quickly! I've done 2 PS lap quilts so far and wish I would've done it via leaders/enders! It'll look great no matter the borders you choose! ;) ;)

This was my Original thought, but I keep second guessing myself! I think I might just go with it and see what happens!

Black a red binding would be pretty

Very nice job!

Have you tried auditioning different colors. I often think I want a certain fabric, then when I audition it, I don't. I try different fabrics and combination all the time. I like to do it on a corner to get a better idea.
