Ok, this is maybe way out there, but:
Say I complete my first deer mount, Maybe the thing looks ok ....but suppose the thing is hideous. Can I rehydrate the whole head, tear it down, clean the form and start over from scratch or am I pretty much gonna have to look at the crappy attempt for the rest of my days as is. Or, where do beginner taxidermists send their first attempts that turn out looking like some sick burro with horns? Is there a special destination for these? How about my mother-in-law's livingroom?
