Hi, I have been assembling what I will need to begin oil painting. Because I already had Graham paints and walnut oil, I hesitated buying the ingredients for the MC medium recipe, but decided to get them and experiment. I opened them today because I wanted to check the odors. All passed my sniffer test until I opened the Venice turpentine. I really hate it's odor. I'm a bit asthmatic so more sensitive maybe, and I wanted a little feedback on it's merits. I don't have to include it do I? I'll be painting indoors without ventilation other than the furnace running.
