What is the best way to get burrs out of fleece? I normally have controlled areas for my goats but this year I have let them free range. My husband's son had been in the hospital six months and we didn't have time to do additional fenced areas. Normally, I go through wherever they are and remove the nasty things and move the goats around. I'm looking for advice on the easiest way to remove the burrs ....before shearing? After shearing? Any tips or tricks?
