I got the pattern from a Finnish blog: http://valaanvillapaita.blogspot.com.br/2011/05/tee-se-itse-valas.html
Even after translating the page to English the instructions were not much help, I mainly had to go by the pictures.
It's made from an old pair of jeans and I sew by hand (Jane is teaching me to use the machine) so it came out kind of rough, but it was well received.
