Not exactly a "well known famous" quilter, but did you know that Sulky offers guild programs and workshops? I have attended both and are well worth the time. Our guild had them do the free motion workshop and it was well worth it. Eric Dexler is extremely knowledgeable and very entertaining. They are back on Saturday for the Daisy Placemat workshop. Looking forward to it.
