I take your point but most newcomers are on a small budget and would not buy a large number of DVD's at what is a big outlay. What would be ideal is a starter pack that would enthuse but also have the ability for the students to take on other projects after the tuition day. Therefore a selection of watercolours, watercolour paper, brushes, etc. would make a very useful starter kit if it is at an affordable price. Take a look at
www.hospital-art.org and you will get the picture. Currently I fund everything from my own pocket.
