I share the same pain as you OP..

But try your best to get to level 34, by that level you'll be able to make fleece with one single sheepskin at 750 exp
This is a magic craftsmanship synth which requires guild support, I managed to grind with this once I was able to.

Sheepskin is also sold by NPC south of the LTW guild in the tunnel @ 1k each
