I would take samples/pictures of different types of things that can be done with a scroll saw: Fretwork, puzzles, intarsia, 3D, inlay, relief, etc. So they realize you can do wonderful things with a scroll saw. At the end of the class, I would highly recommend they join Scroll Saw Village. Prepare a handout that addresses this, plus where to get patterns, and supplies Print out some of the info from resources, on this site, like vendors and patterns sellers. Maybe Woodcraft may not like you listing any of their competitors.
I would expect to see many more scrollers on the east side of this state!! I'm excited. If you happen to run across someone from my area, feel free to give me a contact, To help them in any way I can with their scrolling. I know no one from my area will travel to Spokane for a class, but just in case that miracle happens.. There is another gentleman on here from Spokane who makes hulls for RC hydroplane boats. He is not here often, but I think he still stops I once and a while.
