For this quilt, the top quilting thread will have to blend in with the pinks and variety of blue fabric. I pulled some of my lighter shades of Superior's King Tut 40 wt. cotton thread to audition for the quilting.
The quilting plan is to quilt a grid across the entire surface of the quilt. The piecing seams will be stitched-in-the-ditch and the stitching will extend across the inner pink accent border and the outer blue border. To get an idea what the thread will look like, the strands of the different colors are set on the pink and blue fabric.
