Looks like Sadiemae beat me to it, thank you for putting up the link to Patsy's blog. She is such an inspiration to me, in addition to the trapunto she's also inspired me to experiment with hand dyeing.
Here's a link to Patsy's trapunto video on YouTube, Part One:

If you click on her name you can go directly to her channel, these links just come from my favorites on YouTube. Hope that helps! So glad a few people found her as interesting as I did! :)
