## How do you calculate quilt binding?

How to calculate the yardage necessary for binding

1. Determine the perimeter of the quilt by adding together two times the length and two times the width of the quilt.
2. Divide the number of inches of required binding by 40.
3. Multiply the number of strips (7) by the width of the strip (2½”) and you need 17½” of fabric.

How do you calculate triangles for quilting?

A—To calculate the size to cut a square for side setting triangles, multiply the finished block size by 1.414 and add 1.25″ for seam allowances. (For example, 10″ block × 1.414 = 14.14 + 1.25″ = 15.39″; rounded up the measurement would be 151⁄2″.)

### How do you keep the points on a triangle when quilting?

Save the point by sewing slightly outside of the intersection, just a thread or two into the ¼” seam allowance. 4. Press the units flat before unfolding them to warm the fabric and set the stitches. Open the units and press the seam allowances away from the triangle point to reduce the bulk underneath it.

What is the formula for half square triangles?

The formula for cut size of a square to make a pieced square of half-square triangles is: side of square + 7/8 (e.g. finished square = 2, cut size of square is 3 3/8). Draw diagonal line on wrong side of lighter square.

#### How do you make a square square accurate?

Fold the square in half and finger press to make a light crease. Unfold the square, and then fold in the other direction. That’s the important part- make sure the your triangle point is lined up with the exact center of square! Don’t “eyeball” or guess at that part…
