This nautical art piece is 8" X 10". All the parts are cut from 1/4" thick wood. You can optionally use paint or different species of wood. I think it looks fine with just a single species but you have the options.
Here is an interesting video. Justin Christensen(The Scroll Saw Scribbler) shows his techniques to create intarsia art. His patterns are not the traditional fare. He brings a modern and more youthful design to the art. He gives a lot of tips and suggestions in the video. The video is a bit over 30 minutes but it is well done.
