Hello Irish: Glad to hear that you enjoyed my article. In general, you can apply carving techniques to
any fretwork pattern. However, there are
physical limitations. If you try to carve very detailed fretwork cut from very thin wood, the scrollwork will shatter. It is best to carve on wood that is at least 5/8 inch thick. BUT, as you increase the thickness of the wood, it becomes more difficult to cut a very detailed pattern. So, my recommendation would be to start with a simpler pattern on wood that is about 3/4 inch thick. As you become more comfortable with the process, you can increase the complexity of the pattern and use thinner wood. Always use very sharp carving bits on more detailed patterns.
If you want to see some other projects where I have used carving techniques on fretwork, look in my Scroller Gallery on this forum.
