You dont need to order an form or anythign yet. That deer needs to be fully caped out and salted before you can even get a close measurement but really should wait until the cape is tanned. Then you can get all the measurements you need and get the perfect form. The taxi doing this for you should be able to handle everything once you give them the cape still attached to the head. I prefer it when I get deer like that because I know I wont screw anything up then and the cape will come off with no to minimal holes. WCL
