Does anybody know where I can get directions/instructions on how to use a thermal crayon? 

Hi Cody. Here are some instructions taken from the Neon Engineers Handbook. https://neonmg.s3.amazonaws.com/assets/images/user/2/0353AB4CBED5BEAE847A7FF6E220B5CF.jpg

Thank you very much. I almost emailed you directly, but I figured I would go through the guild. Thanks for the t-shirt and accepting me into the guild.
