Looking for a little help or maybe a point in the right direction if anyone on here can help me out.  I am going on an archery elk hunt this fall and I would like to make myself an open single reed, elk cow call.  Was wondering if anyone on here might be able to provide me with any information on where I might be able to get some supplies to make my own reeds.  Not sure what the name of the material is I think I read somewhere mylar or something of that nature and I think that I am looking for it in thickness of probably .010".  The type of mouthpiece that I would like to make would be one similar to the primos hyperlip style call.  I like this style of mouthpiece a little better than the style that has the reed enclosed inside of a tube, just my preference.  I was thinking that I would probably use derlin to make that actual mouthpiece unless someone on her has a better suggestion.  Any help would be appreciated.  Thanks
