Marti Michell 6.5 x 6.5" My Favorite Ruler - 8973

Gridded using the same symbols as our large rulers, but also with a shadow that follows every inch mark, turns a corner and connections, making it easy to see squares. There is one 45-degree diagonal line to help square up half-square triangle units. The last 1/4-inch is great for checking seam allowance.
