Please note: This calculator is a guide only. Fabric widths, shrinkage and cutting can all vary, so I recommend buying a little extra fabric to be safe. Please check your measurements before you cut.

Based on fabric that is 40 inches (101 cm) wide after prewashing. Squares, inlays and strips are cut across the width of the fabric. Yards are rounded up to the nearest ⅛ yard, and metres up to the nearest 0.1 metre.
