Louisiana Voodoo is often confused with Haitian Vodou and Deep Southern Hoodoo. While related to these forms of the religion, it is a belief system of its own. Vodou, Voodoo, and Hoodoo are three separate things.
New Orleans Voodoo differs from Haitian Vodou in its emphasis upon gris-gris, Voodoo queens, and use of Hoodoo paraphernalia. It was through Louisiana Voodoo that such terms as gris-gris" and "Voodoo dolls"' were introduced into the American lexicon.
Traditional Vodoun doesn't use the word "voodoo doll"...that is a Louisiana Voodoo specific term. :D
SO, if you are looking to make a "voodoo" doll of yourself, I would look into New Orleans style voodoo, since that is where the term comes from.
A friend of mine has made poppets of people out of action figures for the past 30+ years. I have one of myself. It is a very handy thing to have. I can set up a action figure sized circle and do workings through the medium of the poppet. I can have it in a circle of protection or whatever and then go to work and have a projected circle around me, for example.
