Constructing Your Own Set of Tans: Easy Tan Construction:
Use a square the size you want the finished puzzle to be. It can be a square of the material you would like your set to be made of or, if more convenient, a paper template to transfer the design. Draw a four by four grid on the material as shown in the picture. This will scale up or down for any size square, the four squares by four squares part is the important thing here. You then mark off the blue lines as shown. Cut your material carefully along these blue lines. This will produce the seven tan pieces; five triangles, one square and one parallelogram. As noted above, slicing rather than sawing will produce the best result. Enjoy!
