This painting is pretty small, only 3.5" x 3.5" on wood, approximately 3/4" thick. I purposely left them sort of rough to give them more character. I have a number of these small blocks that I gessoed a while back. I love how they really showcase a single object like the sea shell below and how they look on a small easel. I think these would make a great small item to give as a gift.

The photo above shows the depth of the painting on the easel.
This photo gives you an idea of size.
Here you can see some of the sketches I did prior to working in oils.
