Here are some extras: [link]
It's photographs of the result, the old tutorial with photos and a pattern for your own fox tails ^^ (If needed, just send me a PM with you e-mail adress, I'll send you the .rar with all the files separated!)
I wore this costume 3 times, and I had no problems, even during the photoshoot when it was a bit rainy
It left my hands a little bit dirty when I touched my fox ears, but really nothing bad !
Well, I hope this tutorial will help, don't hesitate to comment and give other tips and advices, ask me things, etc
Don't hesitate to ask things and give me feedbacks on this tuto (or post your pics of your colored fake fur on my FB page! : [link]
