Here is how I measure my last Flattie: I have been telling everyone it was 50", but I realize I may have measured it wrong. What is the proper method? Like I did it, or put the tape under the fish on a flat surface so as you are not measuring the curves of the fish? Thanks guys. Either way, I sent the taxidermist the picture of me measuring it and told him to make the fish 50" according to this method. I certainly don't want the mount smaller than it actually was, but I don't want it any bigger either.
