One free with every order containing one other bead roller in May. Three of these shapes are just 5/32nds of an inch larger than 3 of the shapes in Clay Cutter Set 1. Therefore it will be simpler to create "frames" using these cutters in conjunction with set 1. The largest is a 1-3/8" square. This size is nice for mixing smaller color formulas. i.e. 2 squares of yellow and 1 square of red makes orange. If notes are kept of color formulas, then a color you create can be repeated. I highly recommend that people new to polymer clay experiment with mixing their own colors. Use a smaller cutter to get started if you like, then when you have use for one of your formulas, you can use the larger square to mix your clay formula for a project. I just know I got a great deal of enjoyment making a strand of color formulas. I used magenta, yellow, and cyan, the colors that ink jet printers use to mix colors. Those colors do create a beautiful array of colors that go together so nicely. I overcame some fear of what colors would look good together by creating some color formulas by mixing those three "primaries".
