Hi Roy, I would suggest going to "Intarsia.net" and trying the free pattern that is available. It has a complete set of step by step instructions that go with it. Or there are a couple of good books that, along with instructions, has several patterns that will give you a variety of subjects you may like:
1. "Intarsia, Woodworking for Beginners" by Kathy Wise (Kathywise.com)
2. "Small Intarsia Woodworking Projects You Can Make" by Judy Gale Roberts (Intarsia.com)
Or you may want to start out with Segmentation projects first, most of them can be made from ordinary pine wood and painted to look very nice. A good Segmentation book, with instructions, is: "Scroll Saw Segmentation" by Patrick Spielman
Good luck.
