Use Cases

Plan binding for a new quilt

Before cutting fabric, determine exactly how much binding you need and how many strips to prepare, saving time and material.

Example: Quilt 60" x 72", binding width 2.5", seam allowance 1/4"

Estimate fabric yardage for binding

Use the strip count to calculate how much fabric to buy, especially when working with limited fabric or multiple quilts.

Example: If you need 8 strips, each 2.5" wide, you'll need about 20" of fabric length.
