This is my personal opinion.......that border is way too busy for that quilt. With all that's going on there you need a place for the eyes to relax a bit and keep everything rounded up! Maybe two solid colors, closest to,center dark and narrow, like the matting of a picture, then a wider lighter shade for finish and bind in that same color....keep,all that activity in the body of the quilt. Use the " cowboys" for something else........
