A wonderful addition to the Jewel Box family, this tool makes a pentagon with the seams to the center, rather than to the points. While it may seem a subtle difference---it isn't! It gives your decagon designs a whole new twist. Pentagons are not the only thing the Jewel Box GemStar makes. As its name implies, it also makes stars with five points. The stars can be made as floating appliques or sewn into the Gem Ten seams. The packaging includes a Bonus Pattern: the 26 inch square Royal Star pattern and step by step instructions for making Star appliques.
