things that you should be careful with:
--uv resin. That includes gel nails and all nail accoutrements. No you shouldn't gaze into the uv lamp either. I mean it, nail glue will fuck you up. Yes it is now less likely to cause cancer in nail techs due to formulation regulations no it is not zero risk.
--epoxy resin. You need a respirator. Ask me about the bloody and blistering rash I had to treat for months if you think gloves are optional.
--most adhesives in fact there's a reason you can huff shoe glue and get high and that reason is "it gives you brain, throat, and lung damage and you need to do this project outside". Krazy glue is an eye skin and lung irritant. I don't know why you people don't read the packaging.
--solvents. Paint thinner. Alcohol.
--paint. Im not sure why you're playing with oil paint in a windowless room. You don't need to paint your bedroom with the windows closed. If it's raining you can wait.
--wood stain. Ask me about the rocking chair incident.
--cleanign supplies. You shouldn't be mixing them. I know what you saw on the internet. Those people are morons. Are you a fucking moron. You will get turbo cancer. And more importantly bronchitis. Glass cleaner on the glass, lysol your fucking countertops, and pour toilet cleaner or pine sol in your toilet. No. Not both. No you don't need to dump all of them in your sink. Leave the door open while you clean.
--if you have unbaked polymer clay you need to paint it after you bake it. After. Not before. It's weird that I have to specify this.
