I know you are still loading but just wanted to sneak in a comment. First thank you so much for posting all this wonderful eye candy for us.
It never occurred to me that some quilts make the rounds between all these big shows. I don't know why, it does make sense. I saw several of the quilts you posted at the MQX show in Rhode Island in April. The witches brew, the lone star quilt done ala OBW style, the giraffe mom with baby were all at MQX as well as a few others.
You are right, to see this caliber of quilting up close and personal is rather mind blowing.
