I love the meander design for quilting and I would use a rainbow color for the quilting thread - either pastel or bright. Or an ecru. You want to see the meander design too. That is part of the quilt. I find that the quilting is just as important as the blocks or design of the quilt. I just finished a humongous quilt with hummingbirds and Morning Glories (or as my mother used to call them - Morning Glorious) and I used a dragon fly pattern for the quilting. Turned out fantastic. Have fun. Edie
