1. Don't treat the fletched area of your shafts with boiled linseed oil. It dissolves adhesives, and soaks so far into the wood that, even after repeated scrubbings with rubbing alcohol and fine-grit sand paper, nothing will stick to it.
2. Don't decide to boil the alcohol out of your home-made arrow varnish on the kitchen stove when it's -20F outside and the family is trying to get ready for church.
This is why I like trying new things: It keeps me humble.
