Hi Red,
Gosh they are all great! Make an easy border, go from light to dark on the outside, you have every color to choose from, so just pick your favs and add them on. The multi colored prairie points would look really nice, but take a little longer. The whole quilt is so busy, you might just want to do plain borders and call it quits. ha
Do you have any veggies in that garden? I have to go water mine now, it's supposed to be in the high 90s again today. Don't have the drip system set up out there yet. Then it will be on a timer and I won't have to go out twice a day.
Really though, super job on those UFOs :!:
