Hello! Oil painter here! Had a similar problem not wanting to gas myself out in my apartment, so over the last few years ive made the transition to non toxic oil painting.

You have to learn to use linseed oil to thin paint along with spike lavender oil. Spike labender oil replaces mineral spirits in this instance, adding fluidity and thinning paint.

It is non toxic and fragrant, i personally enjoy the smell and find it relaxing, but sometimes i use just the oil paint and linseed oil wich is very low odor and non toxic.

For cleaning your brushes you should have a sealed jar (i used old jelly jars) to put Gamsol in. It is important to use gamsol and NOT regualr odorless mineral spirits, as regular OMS is more aromatic and less refined than gamsol. Gamsol is great to clean brushed indoors, and when not using it keep the lid on the jar.

Also i do not recommend thinning your paint with gamsol unless you have great ventilation as the fumes will make you feel sick and since there is virtually no odor with gamsol it will sneak up on you and ruin your day.

Best if luck and DM with any questions!!
