From what I know of spinning (and, having spun only 3 balls or so, I'm no expert!), the longer it is, the easier it is to spin - but the more experienced spinners can do wonders (i.e., thread) even with short fiber.
The fiber table I've found starts with 2 inches, so 1.5 inches seems doable (and fine wool is usually shorter than coarse wool, anyway), If in doubt - try a little bit, make a small knitted swatch and try rubbing, stretching and washing it. That should give you some idea of how much it shrinks and how much it falls apart.
If that doesn't work or you're not feeling
that adventurous, mix it with something longer - typically, sheep, but it's not a law

- and then you can spin anything. Even cat hair, which is not spinnable, as a rule. I'm sure something posh (like angora or cashmere) was also only spun with usual sheep's wool, on account of being hair that doesn't hold together if it's spun by itself, but I can't remember or find what it was.
I think an encyclopaedia we have says you can spin pineapple leaves (after you've done retting them mercilessly). That bit of information (and a few others, equally ludicrous) was what sold to me the idea of buying that ancient encyclopaedia set that takes half a shelf all by itself. You just don't see such things in new editions
