Hi Joyce
The hat business was a suggestion for taking pictures of all of us in kooky Mad Adder hats. That's all.
And no, no rules.
There was a demonstration on how to sew together small bits of fabric to make a bigger piece that then could/should be added to the flimsy somewhere. Any size, any shape, anything you want to do as long as you have at least 2 bits of fabric-or 3 or 4 bits- sewn together to make a larger one.
You didn't miss much. The video is still not available, but I will also watch for it.
