Would anyone be able to tell me how I can mix a solvent-free medium like used in Geneva paints? Is it possible to get an idea of what medium is actually used in Geneva paints? I saw the recipe that Mark suggests, however it uses OMS, whereas my understanding is that Geneva paints do not contain OMS.
I generally use Spike Lavender Oil if a solvent is needed, so if one is needed for this medium, does anyone know a recipe that I could mix using Spike? If not, then any medium that's solvent-free and compatible with Geneva paints as far as mixing and open time will be great. Thank you for your help!
