Hi Linda - Wow, ya done good! I'm very impressed! Not only is it a solid, great looking walking cane, (which I unfortunately need these days), but it's a well-tuned and responsive flute, (concert pitch, no less).
I've played Irish flute and whistle for years, and have owned some killer flutes. This is, of course, just a cylindrical bamboo flute, and has the inherent limitations. But dollar-for-dollar, it's amazing! I'll be showing it off, and already have my nephew interested in a hiking-stick flute. I'll also leave good feedback on eBay and your website. Kudos to you guys!
