STRING HOLDER

A friend of mine owns a large grass cutting business. If he heard me call it that he may not be my friend anymore. LMBO!But I am a simple man and it is what it is! He came over and was telling me about how they lost so much weedeatting string because the spool would roll off. I suggested this, made it while our wifes cooked. He went home saying he was going to get a pattern and make more. LMBO!(sometimes I wonder!)
