I have a Woolrich caped wool hunting jacket. The one with the large black and red checks. Have had and enjoyed it for 15 yrs plus. Problem is it seems to have shrunk. Particularly the sleeve length. Have never washed it only dry cleaned once. Is there any way to wet and stretch/fluff a wool garment back to its original size. I read somewhere on this forum about "planking" a wool blanket. Would this work? Any ideas? Thanx for your help?---KV
