The supply list will be coming. I took a class with her last year at the Vermont Quiltfest by myself and had a good time. Take the usual goodies, including items mentioned above. Mt Scrappy trips was only a hour class so no snacks, but folks brought a few goodies to share. Bring bottled water, and definitely a pillow to sit on. She usually has music in the background. Camera recommended!
The first 10 minutes of the class is spent helping everyone be sure they have an accurate 1/4" seam, and she sells a needle guide for $2 or $3 which is useful for aligning any machine. Your class supply list will be helpful for getting all your fabrics precut, so it's "pedal to the metal" when you are ready to sew. Be sure your machine is ready, and I always take a spare. The hardest thing for me was to decide what type of fabrics to use.
