I'm glad Ryan resurrected this post. I totally missed it.
That walk up to your house is fantastic. The corn field and scarecrow are really well done. I see what looks like PVC pipes at the base of the corn stalks. Do you have some support rod for them? or is there no wind where you live?
The shelves are a great idea. The same idea would work great for making a stair case or wall to set them on.
