A pattern similar to this?

I have a whole year to try to knit this before the Renaissance Festival comes back next year, and I’d like to try to make something similar to this for the fair. Only thing is, I can’t find a pattern anywhere. I’m not going to be selling it nor sharing the pattern with anyone, but I would like to make this for my costume. Any ideas or help?

Thanks a bunch! I’m going to look through them now.

Enjoy! You might not find the exact same but maybe something you like.
