On my scrappy quilts, I too use a first narrow border to stop and rest the eye. Then either a pieced border or my go-to colour of very dark blue. Dark blue, to my mind, is less aggressive than black, and works well in a lot of situations. I use Hoffman's Tahiti watercolor very frequently as it is dark royal without being too full of black. It allows the quilt itself to be more 'luminous'. Then I bind in the same colour, since I don't want another distraction to the eye, just a quiet finish.

I tend to lean towards my favorite colors when I border a scrappy, where there are a lot of colors. That means blue usually. On the one I just made, I made a small border of a light blue and then a larger border of a darker blue. But, it all depends on what works when I lay them on my design wall. I enjoy selecting the borders. Hope you enjoy the process too.

How about making the binding scrappy like the quilt. I have done this with varied lengths of 2 1/4" wide scraps from the quilt top and it looked real cool. as far as a border goes you have to audition different fabric till you find one you like. If the quilt is 'busy' I use a tone on tone to calm the quilt down a bit. Can you post a PIC?

Normally I do a solid border to kinda frame the quilt itself, but more recently I did blocks in the corners and then a solid border in between. It carried the theme of the quilt through nicely!
