I have two art studios. One is in Idaho. And one is in Illinois.
I mostly do oil painting and watercolor in the Illinois studio and acrylic and watercolor in the Idaho studio right now. It's good to keep the oil paints away from the water-based paints. Although it's not necessary to have two separate studios. It just worked out that way for me. It does help keep, like I mentioned, the oils away from the acrylic and watercolor paints.
One nice thing about summer is working and painting outside. I also do most of my varnishing outside in the summer months. I just have to make sure it's not a windy day.
