There's a class at Quilt University on Shiva Paintsticks. It starts July 8th and is taught by Daphne Greig (remember the quilter whose quilts were marked up by US customs on her way to Quilt Market last year?)
Here's info on the class (click on the supply list for all the detailed info and a class outline). It'd be well worth the $36 registration fee.
