If you did choose to prep this you would discard some of the coarser hairs for spinning, but don't remove too much texture as it would be a shame to loose the colour changes.
I think this would also be very good for feltmaking too and if there's any left I intend to make some batts for blended texture.
As it's not a lanolin rich fleece, it won't take much washing so great to try out if you have never washed a fleece before.
Let me know what you think if you try some.
I shall visit the farm soon, so hope to add a few new breed fleeces to the shop!
