Making you own antelope decoy
 

I am planing a trip out west next year for antelope and am wondering about using a decoy. I will be hunting during the real early season round sept 1 and I am told that they start rutting round the end of the mont so I am thinking maybe something like a cow decoy might work better or since we are thinkin about the Teddy Rsvelt National park maybe a bison decoy.
Anyway want to make my own so if anybody has any advice or pics of there own or advice on how to use them I would greatly appreciate it.

Thanks for all the advice in advance.
