When I bought my studio (an old house that belonged to my friend & neighbor before she went into the nursing home), there were lots of old spice tins & bottles in the cabinet. I hung on to them waiting to use them. Several years later, I figured it out!
I covered the tin with some pages from an old book and painteda creepy tree, added letters from newpaper to spell out "boo", then topped it with a paperclay pumpkin head with crazy eyes! Measures about 5.25" including his stick stem.
