So, i got the 1x1 long sleeve crewneck (http://www.contextclothing.com/item.php?id=2166) and i got a spot on it (not sure what). Is there anything i should know about washing it to reduce stress to the peice? I'm assuming i should hang dry it. Also, I'm on the tall side of things and probably couldnt take much shrinkage, should i be real worried about this? thanks!
