My new pattern using the Catherine Wheel join isn't ready quite yet, but will be soon. My excuses include family commitments and a whole lot of equipment breakdown, including my digital camera. But, it's replaced now. Also, finally, after changing to a different and supposedly impossible transfer setting, managed to get the irreplaceable pictures out of the old one (isn't it Murphy's Law that a camera will break down during a special occasion, not during workaday tasks!)
I've had requests for the Catherine Wheel demo to be made available as still photos, so I will work on that also.
