copperpipe, and sandleafcasting look it up on BHG

Check the Garden Junk forum. There are tons of ideas there for hose guides.
Croquet mallets, golf clubs, etc.

I made mine with the turquoise vintage electrical glass insulators. I silicone glued (with aquarium glue) a bunch of the clear glass half marbles inside with a piece of copper pipe. The insulators have indents in the middle of them, the perfect size for my hose!

Mine are pretty simple. Copper pipe with big marbles siliconed on top. I alternated black and red marbles. It's easy, and it works pretty well.

My are very simple,tent stakes covered with empty propel water bottles.Blue bottles of course.
