Pumpkin in a lace stocking. I've planted a bunch of mini white pumpkins. White lace stockings on them might be a nice outdoorsy Autumn touch. Inexpensive and kinda unexpected. These might be cute on the outside tables under the arbor too.
Pinner says: These are easy to make out of chicken wire! I was at The Gathering Spring 2013 (an antique & collectable show) in Knoxville, Tn and several vendors had these - some had old or stained wooden knobs on top.
