Today's project is one that several people have asked me about: a bottle tree.
This is a custom in the South, whether it's a welded piece of fantasy or just bottles stuck on the branches of a dead tree.
Materials for this one (what I had on hand on a day too snowy to shop for more steel): 6.5 feet of 5/8 rebar, and about thirty two feet of 3/8 rebar, plus a wicked sharpened cleat that you can step on to drive it into the ground, this makes for a steadier base.
Installed height will be 8 feet, with room for 24 colored bottles.
