You know you’ve got CP when…

…knitting in your powerchair looks like this:

A ball of black and silver sparkly yarn (Sirdar Firefly) with a hole in the middle balanced on the control of my powerchair. The joystick is through the middle sort of like a spindle.

And knitting your manual chair looks like this:

The same yarn balanced on my manual chair. The brake is acting as a spindle. The ball is slightly smaller here (it comes wrapped on a ring of card) and the central hole is larger.
