A cape is really pretty quick and easy to do.
I start the cut right where the feathers start on the neck.Begin cut at that point and cut around the neck about 2/3 of the way.Continue the cut along each side of the back,close to where the wings connect to the body.After doing it a few times,you can almost make out a line showing you where to cut.The tricky part is that the cape like to try and roll up on itself when you start going down the body.I really haven't found a way to stop this from happening,unless you had another person stretch the cape tight while you continued the cutting.When you get to the tail fan,you basically cut the same as if you were just removing the fan.Try to get as much flesh/fat off as possible,which will help quicken the drying time.Lastly,I use a big piece of cardboard,and lay down a thick layer of borax.Lay the cape out on the borax,feather side up,pinning as you go,to get the desired shape.You're basically just stretching it out to dry.Make sure to pin the tail fan open so when it dries it will stay open.I let it dry in the borax for a few weeks,changing or adding more borax if necessary,then just dust off good and hang it up.The one in the picture was done about 1994 and it looks like it was done last year.
