DIY kids' art

I'm not especially crafty, but I like making a little creative something-or-other every now and then. For these pictures for my kids' rooms, I drew simplified animal shapes (clean lines + animals: am I predictable or what?) onto patterned paper, embellished them with old buttons, glued them onto card stock, and put them in plain wooden frames. Forgive my poor photography skills:

Why is this bear not smiling? Could it be the flash?

Fish silhouettes are easy to draw freehand.

So are birds.

Paper Source sells some great inexpensive paper by the sheet; the buttons were just castoffs in my jewelry box—you know, the extras you get with sweaters or coats and never use.
