I did mine myself last year. Skinned out the skull and buried it with plastic bags covering the antlers to keep them clean. Dug it up in the summer and had a little bit of tissue to remove. Then I took it and put it in a dishwashing bin with 40 volume peroxide (this can be found at any hairdresser supply store) and covered the areas that weren't submerged with paper towels soaked in the peroxide. It bleached the skull out really nice. I put it on a plaque and you can't tell the difference between it and the one I had done professionally.
