Have any plans for an upside-down tomato planter?

Hello there,
I'm wondering whether anyone has seen those "topsy-turvy"-trademark upside-down tomato planters and have wondered if there's not a way to make one of their own and has already done so? If you have...a hunger-supporting group of gardeners that supply tomatoes, herbs, and peppers and more to the local food pantry really need to have about 10 built or we will build them ourselves (unless someone has the time to help out!) if we only have plans and a list of materials? Thanks alot! You can Email me at thorandkevin@comcast.net if not a subscriber.

Sincerely,
Thor
