I agree with Sunnye... depending on how it's used once you've finished might factor into your decision.
Kind of like the green for a border around the star. OR, can your border be made like the strips at the top & bottom (minus the pink)? Sometimes I place different color fabrics around the quilt... then leave it for a while and come back to see which color strikes my fancy. Let us know what you decide.
**Krista, we were posting at the same time. I too prefer the border.
