I spent today compiling a list of fursuit and crafting resources into a hopefully comprehensive list! I plan to update this list with more information as I find it -- and I will also be accepting submissions to it as well! If I missed including your favorite tutorial or website, leave me a comment!

I really hope that this list can be a go-to resource for people starting out building fursuits and costumes. And I have been meaning to compile my own list for many years.
Enjoy!!
