The painting at the top with the Amish buggy is painted on the lid of a wooden box. I used acrylic paints and then I spray varnished it to seal & protect it. You can call it "functional" art because you can store a little something in the box.Both of the rock paintings are also done using acrylic paint & spray varnished as well. The Garden scene is regular oil. I did this scene quickly as an impressionistic style. The Tawas Point Lighthouse is water mixable oil on stretched canvas. It is quite a large painting & encompasses the lighthouse, sign, store & walkway.
