That´s quite easy way to make a tail because you don´t have to use elastic band or metal etc.
The tutorial is written in baaaad English because I don´t know the correct terms in English, I apologize. But it has lots of pictures so I hope it makes sense. x3
Curly tail patterns can also be purchased from me! This is for people who doubt they can make a pattern on their own. :3 The price is 13 EUR (~19 USD) and it includes international shipping and illustrated sewing instructions as well! Please e-mail firstname.lastname@example.org if interested.
