She actually is selling to Canada. They even followed up my emails inquiries with a personal phone call. They are amazing to work with! I ordered the whole set because this is what was explained to me:
Each DVD taught in the series of 6 DVD’s introduces a new medium. It is a thorough enough intro that each child will be able to see what medium they are particularly drawn to. The 24 lessons are enough to use as a curriculum (once a week I believe) for your whole school year.
The reason I was given for using the entire set as opposed to using the two easiest only (pastel and pencil) is that the lessons are intended to be done once a week. The child looks forward to the next lesson, but doesn’t have long time gaps where concepts can be forgotten.
They are so helpful though…check with them! They’re happy to answer questions. I can’t wait to get my set and begin. Oh yes…and share them with my children too 🙂
