There are 2 posts on how to make this DIY Hand of Glory. That’s because theses are very detailed tutorials with lots of photos. As the author states on Crafster:
I made mine using traditional corpsing techniques, by applying liquid latex and toilet paper on a skeleton hand armature, which I made using crappy, cheap markers, hot glue & string.
The Hand of Glory is the dried and pickled hand of a man who has been hanged, often specified as being the left (Latin:sinister) hand, or, if the man were hanged for murder, the hand that “did the deed.”
Old European beliefs attribute great powers to a Hand of Glory combined with a candle made from fat from the corpse of the same malefactor who died on the gallows. The candle so made, lighted, and placed (as if in a candlestick) in the Hand of Glory, would have rendered motionless all persons to whom it was presented. – Wikapedia
