Those look great. I would really like to make one for my 7 yr old son. I am headed near a military supply type store tomorrow. About how much cord does it take to make the smaller sized ones?. I have never looked into buying the stuff before so not sure if it comes in a bag or by whatever measurement you want. I have looked at a few tuts on you tube. Is there one that you preferred? I watched one with a military/spec forces type of guy making one (well it was from the neck down, so I am basing that on the t-shirt he was wearing...lol).
I think they should sell great at your upcoming show! Different colors and sizes...you can't go wrong.
