Collect with me some idears for drawing-exercices.
With children or adults... like:

+)watch an object for 5 minutes and then hide it.
try to draw it by looking at the picture in your head....
see what was left of it in your mind.
then start again

+)Sit in front of a person, take a pencil and a piece of paper.
Look at the person while sketching him, without never ever looking on the sheet!
(He can do the same as you:Watching you and drawing a sketch of you without looking at the paper!)
Always keep the pencil down on the sheet until you finished the drawing. Try to see "in lines" , your eyes must "go watching " around everywhere in the face!
The hand holding the pencil is driven by the eyes which are watching...
Do it several times,it gets better and better,because you learn to watch..Don't try to sketch by memory!!
PS: sorry my english is a bit ...not in exercise :O(

please write in french, german or english,or luxemburgish ;O)

The idears can be more complex too;O)
