A little bit of applique, and some quilting in a heavy thread matching the applique, add some boring background quilting in normal weight quilting thread to match the background.
I could live with that!
Keep in mind that with the improvement of sewing machines it is becoming easier and quicker to quilt lines a quarter inch apart all over a quilt. Modern wadding is bonded, and some can be fused to the quilt top, or back. It doesn’t need to be near as heavily quilted as cotton straight from the boll. (That is the pod which holds the cotton ‘thread’ on the plant.)
We need some to add the third dimension, but if we over quilt something we plan to sleep under, it becomes less cuddly, and less warm.
Save the heavy quilting for something planned to hang on a wall.
