Thank you.
Um.. do you have a "tandy leather" or suchlike near you? They can set you up with the proper weight of leather and tools as well - and it's easier with someone standing over your shoulder than ordering online.
Failing that, you need:
* heavy vegetable tanned leather. Easier/cheaper to go to a leather store as you can hunt among pieces for the right size. Otherwise you might have to order a whole half-hide or something, which adds up fast. Same for shipping. Depending on the technique you use and the width of the blade though, you might be able to get by with ordering two 2" wide belt blanks and using this technique:

* some means of spacing sewing holes. You can get a fancy tool for it, or just use an old fork.
*some means of punching sewing holes. The specialty punches are best for this, but you can use a hammer and nail in a pinch.
* a mallet to hammer with and a flat surface to work on, like a board.
* some means of cutting the leather. Again, there's specialty tools but an X-acto type craft knife works fine, just takes longer.
now personally I think the "wrap around the blade, sew along the back side" method (like you see in that Sting scabbard I made) looks prettier, and is less bulky that the "sandwich" construction. The downside is you can't use belt strips, you need a wider piece of leather. And a sharp sword may in time cut the inside mouth of the scabbard open more easily.
Really though, since you're covering the whole thing with fur it won't really matter which way you go. Finally- that fur looks like coyote to me, which is considerably cheaper than wolf (not many wolf legally killed these days, while coyote are everywhere). Since that's what's most visible, I'd be inclined to find a coyote pelt for that project - prolly be in the $40-80 range.
