A lil late, but still useful. Hope this helps any cosplayers out there who need bird tails...and a warning, if you're using a high-temp gun, be careful not to burn yourself! The low-temps won't hold the feathers as well, so you WILL have to use needle-and-thread to secure the feathers, but if you use a high-temp you really won't have to.
Anyway, I keep referencing a belt because the belt is what will make your tail stick out at a 90 degree angle from your bottom. I'll try to make a tutorial of it this week, but I don't have a digital camera, so I'm just going to take photos with my film and see if I can get it developed in time. If not, I'll draw it out on Monday. It's much easier than this bit, it just takes a bit of thinking.
Oh yes: and while in this example I did use felt that matched my feathers almost perfectly, you do not need to do this.
With my first tail I used baby-blue felt instead of this nice darker turquoise, and used a marker to darken it a bit. When you put the feathers over it, it doesn't show--so don't worry about matching the felt color exactly. As long as the feathers on top are thick enough, it will not matter. Experiment a bit and find out what works best!
