Wool and cockleburs were made for each other. i should change my handle to Johnny Cockleseed, there is a huge patch that i think I am responsible. It is where I pulled cockle burs off when I got to my favorite valley. It pulls off of whipcord better, but burs will stick to anything. Now those nasty tiny tick sized buggers that come off on a single thread sized stem. They have pretty little flowers in the summer that turn into little devils in the fall. I have given them many names, I am sure none of those names are the correct ones.
