Sheila:
I love your project! I just recently painted some PVC pipe and used glass light shades to make a couple of planters or candle holders for the garden ... they could do double duty as hose guides as well. I love what you did with the one in your photo, I'm a bird fanatic and that is just sooo cute I might have to copy it!
I think you should post a tutorial on your wonderful project over on the Garden Art Forum:
