Meet the Calligrapher: 
Hello! My name is Joan Thompson. My husband and I have two children whom we homeschooled  for over 14 years. Throughout those years, I continued to pursue my interest in calligraphy as an art form and as a medium for sharing God's word. I especially enjoy the historical aspects of the craft, and have taught calligraphy classes for children and adults. If you have time, I'd love to have you take a walk through my gallery, where I have put up some of my favorite work.
