This project map grew up to be a real kit! For more information about the project, I encourage you to read its entry on the project maps page.
Remember that this is only one possibility for a graduated birdcage. If you want to play around and discover your own patterns, I recommend a sampler pack of good Birdcage rings in every gauge from 22ga through 10ga.
Please note that the copper version of the kit works up closer to 17 inches.
Please note also that the rose goldfill and white goldfill versions of this kit contain yellow goldfill clasps.
