My cousin made this loom for me years ago, and I've never used it. (The only weaving I've done is on pin looms and I successfully did one card weaving project.) Anyway, the loom needs a heddle and I'm not sure what kind to get for it. Also, I'm not sure what else it needs, if anything. My questions are:  1)What kind of heddle should I get? (I've measured the width between the sides and it seems that a 10" heddle would fit well.)   2)What book or instructions would be most compatible with this loom? (Is it a 2-shaft loom?)  3)Does it need any other parts besides a heddle?  Picture attached.
