This is what I would do.
With the last (2) panels, sew the right sides together but with the batting on one of the wrong sides. Leave an opening somewhere along the middle (not your corners) Sew & Turn it inside out like making a pillow case, and then top stitch the image(s) to emphasize the image.
Add a curtain ring or something to hang it inside your kitchen.
I like the Kid's print, it's really cute.
