Smaller drawings made of stainless steel so they stand on their own. I go back and forth between a) making drawings of sculptures and b) making sculptures of drawings.
These are the b variety, and are actually a page, each. Their outlines are generally that of a piece of A3 paper. I then mentally fold, pierce or shape them and draw how the outline with then appear, and make sure that some element in their composition will allow them to stand up. These paper drawings in steel are very light (and relatively inexpensive to own). Their shadows are nice, too.
