Tru-Grid patterns are thinner and easier to store than most purchased patterns. Its sturdy enough to write notes along the sides of patterns. It clings to the fabric when you lay it out, so few pins are needed. Because it is fabric, you can pin a mock-up of the garment for testing (which would be awkward with a paper pattern) Tru-Grid is wider than most tracing papers, much easier to handle, and doesnt rip easily. It will last longer than any tissue pattern, so if you have a favorite pattern that is falling apart, or one you think you will use a lot, this is a more durable method.
