Homemade Upside Down Tomato Planters

These worked pretty well last year.  Wanna give some a try?  Materials used are paper bag for lining, twine, empty 2 or 3 liter bottles, smaller empty bottles for inverted watering, fertilizer, dirt and a tomato start small enough to carefully fit through mouth of bottle.Both the jumbo and cherry varieties did well.

Suggest hanging on the porch entry so they get enough water.  Had 6 along the entry last summer. 

Any aesthetic & inexpensive water efficient ideas that don't require a step ladder this time round?
