"Brown paper packages tied up with string"

Prismacolor colored pencils on Stonehenge paper

approx. 14" x 14"

Walnut shells appear as if they're hiding something wonderful inside. It's no wonder that miniaturists have used them as fairy cottages, or beds for mice, and that silversmiths have outfitted them with elaborate hinges and clasps. 

There's nothing miniature about this drawing—the live image is about 7" x 10".  I have it sitting on a ledge in my studio next to this piece; they work really well together:

Mine sort of evolved as a version of a "brown paper package tied up with string". 

What do you suppose is inside?

Here are some progress shots; I kind of experimented with ways to render the walnut as I went. (I found it to be much different than drawing one at its actual size!)
