Strips, yardage, regular/bias, flange
Work binding math in either direction: the yardage to buy for your quilt, or the binding you can make from fabric you have.
Tells you how much yardage to buy to bind your quilt.
Mode
Strips cut parallel to fabric width (straight grain).
Typical: 42" or 43"
For mitered corners and joining ends
Join your strips with diagonal seams — they distribute bulk better than straight seams and virtually disappear in the finished binding. Sew corner to corner, trim to 1/4", press open. If you're sewing them in the wrong direction and getting V-shapes instead of a continuous strip, flip the top piece and try again.
Always buy a little extra. Running short on binding fabric with a finished quilt in your hands is a special kind of painful — especially if that fabric is discontinued. Round up to the next quarter yard. Your stash will absorb the leftovers.
Machine the front, hand-stitch the back. That's the standard finish and it gives the cleanest result. Mark your 1/4" stop point at each corner before you start sewing — clean mitered corners come from stopping in the right place, not from the fold itself.
Turn this calculation into a project — track fabric, materials, and progress through to the finished quilt.
