I would go with lime for inside border, plaid outside border and dark brown binding.

Sound like you have it covered, I like what you have done so far...

I think I would go with a thin green, then wider border in the plaid then bind in brown.

I'd go with a yellow for a thin border, then plaid, and bind in either green or brown

Ditto on this idea. Except for the brown for binding. I might go for the green again for binding too.

Thin green border then plaid,

You've had enough suggestions. I just want to tell you it looks great

I agree with this one.
