The MKM Decorating Disks™ for Clay is a set of two sturdyflexible transparent sheets. Each Decorating Disk has it's own even or oddsegmented divisions. Use the concentric circles to quickly center your piece.Colored radial lines indicate even divisions, (2, 4, 6, 8, 10, 12) on onedecorating disk and odd divisions, (3, 5, 7, 9) on the other decorating disk.The secret is the holes. Along the radial lines are holes that allow a potterto mark through the decorating disk to the soft, leather hard, or bisqued clay.Place an MKM Decorating Disk on top of, (or underneath) the pot, center it andmark through the holes to the clay.
