Super-Sized Upside-Down Planter

Step 1 Section the bottle

I used 3/4" masking tape to mark off a cut-line along the last clear section. This leaves a lip for the "lid" to grab hold of. Many of the planters I've seen people make don't have any form of lid so they are more prone to evaporative loss.

I used a metal cutting band saw but you can use a hacksaw, snips or a strong pair of scissors.
