Suzanne,
After seeing Barbara's post that the blocks are 6.75 inches, I thought, what will be the best way to do it if you want edge turned, machine stitched applique.
The first thing that came to mind was Ricky Tims Stable Stuff. Print the design on the inkjet printer, cut out on sewing line. glue stick to back of fabric, cut 1/4 inch
larger on fabric, (fussy trim the tight areas), use Apliquick tools to edge turn with glue around edge of piece. Since you can leave the stable stuff you just put it on
the background fabric and machine stitch. I sure their will be lots of ideas coming up on the forum on how quilters will approach it. HelenW
