Pretty! I'd be inclined to find a variegated thread with all those colors in it. Superior Rainbow (Polyester - no lint) or King Tut (if you prefer cotton).

The Brother sewing machine reps at several Sit and Sews I've attended recommend polyester thread vs cotton or rayon. Same sheen as rayon, but no lint and more colors.

I have to agree with the light or medium gray thread for the quilting unless you could find just the right variegated to go with all these colors. And I also agree with laying the possible choice of thread on the top to see how it looks. This usually helps me make a decision. Quilting wise I think I would echo quilt lines several times around in the middle of that four patch area between the melon slices to emphasize it and them maybe even quilt the melon slices like leaf veins. That may be too much for you or the quilt though. Good luck!! Oh and lovely quilt and nice work!!!

That is simply beautiful! Great job!!

I agree with Gunny - invisible thread would be good because it wouldn't take away from the beautiful fabrics you used in the quilt top.

Varigated for sure....beautiful quilt!

Very pretty.

Its awesome, love all your colors.

That is *so* amazing! :D

Beautiful quilt!
