This quilt was made by Bonnie for her granddaughter. The pattern is called "Full Spectrum" by Rebecca Boline. I quilted this same pattern for Bonnie last year. She used a slightly different backing fabric and I changed a bit of the quilting, but kept much the same.
I used a variegated thread on the rainbow stripes, and Maginifco on the black. This is such a happy quilt that I'm sure there will be smiles all around when it is received.
