Great quilt. I would probably pick a bright variegated thread that has many of the colors in the quilt, with maybe black in the bobbin. I'm weird in that I like using variegated thread when quilting.
if you are wanting the quilting to pop, then I would suggest a gold color. If you want it to blend in then maybe a grayish color. I would say go with a gold color but that is just me.
I agree. Best to go to a store and dribble the thread over the quilt. That is what I do when in doubt. Be sure to re-clip the thread and put it back neatly when done.
Love the mental picture of dribbling the thread!!!!!
