First of all that quilt is absolutely gorgeous! Kudos to you for color choices and for the overall piecing and design of that quilt.
A few suggestions: I would use two maybe three different colors of thread so that the quilting really pops...green variegated on/near the purple; purple variegated on/near the greens and because of the color choices for the arcs there are so many other choices for color. I would keep it in the variegated so that there's depth of color. Looking at the color wheel on line blues, reds and oranges would work on this quilt. The fun thing would be finding the right ones that make the quilt sing.
I would also do some serious planning for the quilting before getting started. This quilt wants something that will truly compliment the incredible piecing. Because of the arcs (spikes) something soft and because of the curves (circles) something that will attract attention. If you have any vellum or clear plastic that you can try different ideas out on that would be great.
I can hardly wait to see this finished!

Happy Quilting!

Greetings y'all!
In my profile I have posted a green quilt top in my personal pics. It's for my youngest boy--it's his heirloom quilt. So far I'm really liking it and so is he! I bought some beads that I plan to use for embelishment. Right now I'm stumped for the quilting. I'll probly use purple verigated thread if it'll show up. The top isn't very big so machine quilting won't be too much of a wrestling match. So...anybody out there got any suggestions? Y'all are my guild and my bestest quilting buddies! I'm counting on you!
Thanx much!
