Choose the right size for the quilt-support matters for well do the quilt. The back of the quilt must be at least 4 inches bigger in every way than the top. So, you add 8 inches to the width and 8 inches to the length of the ended top, for find the needed size.
Typically the support usually goes over in 4 inches all around, for leave room for the quilting. If you will send it to long-arm quilter, need 4 inches of extra fabric at every way. Some longarmers favour even 4 until 6 inches here.
How to Measure Quilt Backing
You can also think: add 10 inches to the length of the top and 10 inches to its width, when you send to longarmer. For instance, for top of 80 in 90 inches, the support should have 90 in 100 inches.
Many ways exist for get the right amount of fabric. 108-inch broad backing simplify the cause, because it stops the need to piece the back. Wideback fabric goes up to around 120 inches.
For queen size quilt is fine 3 yards of 108-inch backing. For queen you can use 6 yards. Lap quilts range, but 4 yards should be enough for most.
Three yards of 108-inch broad fabric, cut in quarters, give four 54-inch squares. Here a good way for four small quilts, as laps, table covers, throws, toddler and crib quilts. Lacking fabric?
Pieces piece together. One chance is add a strip of fabric down the center between the widths. For instance, if your quilt top measures 99 inches wide and 106 inches long, the back needs at least 103 by 110 inches.
That happens by adding 4 inches at every way. For 108-inch broad back needs at least 110 inches, so around 3.05 or 3 1/8 yards.
Calculators remove the guessing for find the yardage. Enter the dimensions, and it shows the size and how yards require. It works for many fabric widths, as 42, 44, 58, 60, 90 or 108 inches.
If the fabric is less than 34 inches, one piece of 42-inch fabric works for the support. For very big quilts you sew several pieces together. Take 6.5 yards of 56 until 60-inch fabric, cut it in half and sew for the right size.
For instance, 68-inch broad piece cut into two parts of 34 inches wide in 88 inches long, that sews together.
