Since I do all my quilting on my home machine, if it were mine, I would begin with with a SITD square grid. I might stitch 1/4" from the curved seam. From there, depending on where the quilt is going, I might put a FM flower, heart of=r something in the 1/4 circle. All of that is based on MY preferences. You surely have your own, however.

Gorgeous quilt!

My husband was walking through the room and saw this picture. He says "WOW! That's a nice one!" I like it a lot too. Also afraid of the circles :(

I think this is beautiful... suggested name "water bubbles"

I think an all over meandering stitch would work great.
This quilting would not take away from the pattern of the quilt.

the colors are fabulous

So pretty! I just love that color combination.

I think a grid would be just fine. I was taught to quilt curves if all your blocks are straight lines so I would think if your blocks are curves than the opposite would apply. Love your colors. Sorry, I couldn't think of a name.

I was thinking Circles of Love, because I would really have to love someone to make circles like that.

Wow, this is really good. I can see why this would be difficult to make. I like "once in a blue moon".
