Piecing Your Backing:
1. Measure the length and width of your quilt.
2. Add 8 inches to the length and width. For example:
Width – 72” + 8” = 80”
Length – 96” + 8” = 104”
3.Then divide the length by 36 inches (to figure out how many yards are needed, and 36 inches is equal to one yard). In the example below you can see that for the length, we’d need about 3 yards.
104” divided by 36” (1 yard) = 2.88 yards (just round it up to 3 yards).
4. In the above example, we have 80 inches, and the width of fabric usually comes in 45 inch width. So, we will need an addition 3 yards to cover that space as well.
5. Fold your backing length wise, then in half so you can cut it into TWO three yard pieces.
6.You now have two pieces that are about 3 yards (about 104 inches) x 44/45 inches.
7. Cut your edges to be nice and clean.
8. Then sew the long edges together using a 5/8” seam allowance.
**This is the ONLY time you ever use a 5/8” seam in a quilt.
9. Sew and press the seam OPEN and your backing is ready.
**This is the only time you’ll press the seam open.
** Doing it this way, you will have more then the required extra 8” (4” all the way around the quilt top gives the long arm quilter plenty of room for the machine rollers, if that’s the route you decide to go).
