I would like some opinions on a trout form. I got in a brown trout,my first one. Measured from collarbone to base of tail. Which was 15 1/2 in. So I ordered a general trout form that was a 1/2in. shorter to get the girth right. After I skinned it and test fit on form the skin was 2 in. to long for the form I got. It is like the skin stretched. Is there something I can do to fix this or do I need to get a different form?
