Oil painting is the act of illustrating with pigmented drying oils - hence its name.

Recently, water-based oils have become the go-to medium for many oil painters. However, one must be patient with oil painting: with such a delicate and sensitive medium, a drying period is necessary for all portraits. Learn all about oil painting with lessons through HeyKiki!
