Well, Clothing is considered a nessisity by many.
This form of taxidermy is mostly for the sport of it, and or for the decoration of one's home. Neither are required of us. Cloathing provides us protection from the elements, such as wind, cold, rain, snow, yadda yadda. We can now make synthetic fibers, and use cotten. Animal leather is more along the lines of luxary, which in my mind isn't wholey needed.
If it is needed, and used for the purpose that you require of it, then it is okay. If you do it just for the heck of it. Well, refer to Ecco's post at the top of this segment of the thread. *chuckles*
