First off, I love this quilt. It looks like it was hard to do. What size is it?

I would do a narrow white border and bind it with one of the bolder colors from the quilt. I also think just binding it with no border would look nice and I'm leaning toward either a white binding or one of the dark colors from the quilt. Depends on whether or not you want to make it larger or like the size it is.

Can't wait to see the finished quilt.
