The Sunflower's Are Blooming

But I have a problem! My gardening book says that I need to cover the flowers with cheesecloth and they're so tall I don't know how to reach them. So, even if the birds don't eat all my seeds, I'm not sure how I'm going to get the heads off when they're ripe. Blaine says he thinks they'll drop, but he doesn't sound really sure.

Maybe I could hoist the cheescloth up on some kind of pole contraption? Or maybe a pillowcase or a paper sack or something? Hmmm...this will require thought.
