"That which can be smelled upon entering the house." No doubt dreaming of jumping on the furniture or chewing up socks, toilet paper, napkins, aluminum foil, small tin cans, dead squirrels, small pebbles, lint, hair (human and dog), cotton balls, panty hose, Lego's, pencils, pens, and AA batteries.
Started with a pen, but didn't realize that the ink had become too thick to get a decent stroke. I switched to a brush and needed to dip it after every stroke to avoid instant dry-brush. I've since watered the mix down a bit.
