These are the latest Sharpie on cardstock pieces I've done since about October. Yes, it's good to get back to them BUT I've also re-experienced how unpleasant the small of the markers are when using them and the nasal and throat irritation it causes. Basically, the alcohol in alcohol markers is ethanol. As the markers are used, the ethanol evaporates and becomes a volatile organic compound (VOC). It is the vapor from the markers that is problematic. So personal protective equipment (PPE) is needed unless you can work outdoors or in a very well-ventilated indoor space. That PPE involves having a respirator (with appropriate filter) and gloves. So doing more of this kind of work is on hold -- until I'm able to work outfitted with the PPE I ordered today.
