I have discovered a replacement for OMS. I know some of us do not want to use OMS because of the toxicity factor. Some of us have been looking for a replacement that is archival.
Lavender Spike Oil https://www.amazon.com/Chelsea-Classical-Studio-Lavender-Essence/dp/B00N1EFQGK/ref=sr_1_2?dchild=1&keywords=lavender+spike+oil&qi d=1594705268&sr=8-2
It has been used for centuries in oil painting and color pencil work. Comes highly recommended in the oil painting groups and the adult colorists groups.
It is pricey. I am sorry if I caused some of you sticker shock. I did buy a bottle and I hit submit super fast before I would change my mind.
Mods- If I put this in the wrong section. Early apologies.
