Any of your options would work. I think my choice would be to do the narrow fold to front binding with the green.

Here's a link to the pattern http://www.quiltdesignnw.com/q217-mr...lt-pattern.htm

Like the flange idea too and can do a 2 colored binding sing 1" for front and 1 1/2 for other piece.

here's a link to the flange binding here on the QB http://www.quiltingboard.com/tutoria...ge-t77821.html

Pm me your email and i will email you pix of two green batiks that look close to yours. You never know one of them might work...

Beautiful quilt. Isn't it aggravating to run out of fabric!!!

Sometimes a wallhanging does not need a binding. Can be distracting IMHO. Here is what I use in those art type items.

Have you "auditioned" different fabric colors/choices?
I'm one of those needs to be weighted with a darker border.
NO MATTER what you choose to do, it's beautiful. Great work!

I'm not sure it needs any binding at all -- maybe depends on where it's going to go? I wouldn't mind there being a binding but I like it just as is.

Exceptional work!

I like plan B.
