Magic board - cord too short for left-handers

Left-handed kids need to grip the pencil on the right - why isn't it center handed?

Left-handed children cannot paint well on their left side with a cord that is too short for them.

In many cases, this leads to them looking at other children to see how it's done and abstaining from doing it with their right hand!!!
This in turn can lead to children changing from their congenital left-handedness to a pseudo-right-handedness with health retraining consequences :o(
