At Quincy's Quilting we measure and cut our fabric in metres. A true metre is 39 inches; to make the math easier, we measure our metres as 40 inches and then cut and sell our fabric in 2" increments. The smallest cut we will make in store is 4" or .10 metre. Online the smallest cut you can order is half a metre which in our case is 20 inches.
Our fat quarters are cut 20 inches wide by half the width of fabric which is typically 20 - 22 inches.
