These are adorable quilts.
I can see why you would want to make them. I made something similar [url]http://www.quiltingboard.com/t-22863-1.htm[url/]
I had gone to the library and got as many books as possible on construction trucks, then simplieifed the sketches and made appliques.
The quilting stitches were free motion, wrench, hammer, nail, pliers, etc.
This may be a possibility if you can't find the fabric.
Good luck. Be sure to show us what you make!
