If you're not a member of The Artisan Life yet and would like to be/want the mermaid tail pattern referenced in this tutorial, here's where you can download it!
This pattern is for personal use and small-scale commercial use. For example, making some for a local craft fair is fine. =) However, please do not redistribute the pattern - just refer folks back to my blog or this listing so they can download the pattern for themselves!
This file is free, but you are welcome to leave a small donation if you'd like. =)
