Intarsia, to those who are unaware, is sort of like a puzzle for adults and woodworkers. By piecing together serveral parts and contouring the edges of those pieces, varying the stain colors (or types of wood), and then affixing all pieces to a backboard, depth is acheived. The dolphin intarsia project these patterns will help you create is 10" high by about 14" long. Full size patterns are provided. 15 pieces. We have a nice DVD presentation on the intarsia process.
