I've taken several watercolor workshops at Dillman's Sand Lake Lodge in Lac du Flambeau, Wisconsin. Nita Engle (not sure if she's still teaching) John Lovett, Ted Minchin, and Janet Rodgers. Vincent Chiaramonte for portrait in pastel and oil. All of the instructors are great, the facilities are beautiful in the north woods of Wisconsin. Classrooms are well lit, with big windows facing the lake. Overhead mirrors and overhead lighting. I first met Nita Engle in a workshop headed up by Jack Hines and Jessica Zemsky in a camp by the Bolder River in Montana (an hour or so from Big Timber.) Nita said to me "Linda, if you want a great workshop painting experience go to Dillman's. Good advice! I did have one awful experience with a female portrait artist who's name I would never mention, but even then I did learn a few things. You really do learn a lot from spending a week at a workshop. Ted Nuttall is next on my list!
