Beautiful quilt.

Wow! That is one beautiful quilt. I think I would use variegated thread to quilt it. I really truly love it.

I'm kind of thinking baptist fan with a variegated grey thread.

I agree with variegated thread, but get some that's really colorful. Or maybe use a gold thread... That is a GORGEOUS quilt top.

Wowser! Think I'd use a variegated thread in primaries~

I'm not sure what advice I could give, but I REALLY love the top!!! :) Whatever you decide to do will look gorgeous!

Yes, that definitely is a happy quilt. Made me happy too. Thanks for sharing. I think a variegated would be a good choice as well.

Definitely yellow!

I'd be tempted to do spirals in varying sizes to pick up the round motif in the blue fabric. Maybe start on top of those in the fabric and work out. Or if you want to be really fancy, do the wiggly lines as suggested elsewhere but throw in spirals as an interruption. No suggestion on color.

Absolutely variegated thread -- its a gorgeous quilt!
