There are many painting choices. Watercolors are great — transparent, safe, portable and fast drying, and for over 20 years they have been my “go to” medium. Gouache is similar to watercolors, but opaque, so it’s easier to cover mistakes. Acrylics are also opaque, with the appearance of oils when dry, yet water-soluble. Water-soluble oils are non-toxic with easy cleanup.
After years of hesitation, I finally bought some regular oil paints. My brother-in-law Gordon assures me they can be used safely by cleaning brushes with baby oil. The main difference is the slow drying time, so you can make changes for days. Here is my first oil painting — so fun!
