craftgrrl | Questions on spinning...

You guys are always such a help! :)

Okay, for the fiber-artsy-folks...

...say I have some other fiber. Like coyote fur, donkey fur (if that's even possible? it's so much like hair), dog fur, or tanuki fur. And I want it spun to make string/yarn for necklaces.

How much raw fiber do I need in order to get a good amount of yarn/string/braid/whatever? Say at least one yard, though preferably a few yards. AND is it possible to "draw it out" (if I'm short by a few ounces) by mixing it with wool?

Also, it may seem straight up but I'm asking just in case... once I get to the string/yarn part, I pretty much just cut it where it needs to be cut right? Then crimp the end into a metal necklace-bit (that latch part... guh, I need to learn this terminology!). Right?
