Here's the link to the tutorial for the bowtie block that the YoYo's were demonstrating. Mom gave me permission to post it here. They spent hours with folks learning how to do this...she even had a couple of Japanese quilters who didn't speak a word of English who sat with her and learned how to do these perfectly.

also, the Scissor Man is always thrilled to see the YoYo's...here he is with Mom.
