sketch your whole cloth quilt design on paper- start in the center with the building- then perhaps put your feathered heart corners in---then (using a pencil so you can erase/change) start trying out filling in- you could cross=hatch, do a tiny fill stipple, lots of options- but since you need to draw it out (mark the quilt first anyway) start the design on paper- working on paper until you have exactly what you want it to be--then you can add/tweek/try different ideas until you have it just right...then from that sketch you can enlarge it to mark your quilt top for stitching.
