New Art on Display

The newest piece of art hanging in the Henry County Courthouse was donated by Jodi Haars of Geneseo. Jodi's main artistic outlets have always been music, classical dance, writing and merchandise display. She was encouraged to pick up graphite pencil which led to colour pencil, then to watercolour which is her favorite medium to date.  She is also interested in line and wash and pastels. Coming so late to these mediums has been both challenging and satisfying, as there is so much to discover. She continues to learn and grow enthusiastically.
