Your Visualisation Kit contains 144 viewing cards. These are graded through five levels: Beginner; Novice; Competent; Expert; and Professional. There is deliberate progression through each of these levels.
For those who want additional challenges, we have created extra card sets. Set #2 is available for download below (follow the printing instructions supplied with the download). These additional card sets can (in due course) be purchased - see order form for pricing and details. Further sets to follow.
