These are some of the observations I’ve made over the years regarding backing fabrics:
- Selecting Backing:
A dense quilting pattern works best with a patterned or ‘busy’ backing- detailed art quilting works best on a patterned or busy backing- the quilting will show most clearly on a plain or small print backing fabric - Measuring Backing:
The ‘draw-up’ on a quilt is affected by certain variables like the type of batting and the density of the quilting, therefore it is essential that all quilt backing (and batting) are at least 8 inches wider and longer than the quilt top. If you prewash your backing be sure to square it up and measure it after it comes out of the dryer. - Backing and thread colour:
Usually thread is chosen to match the quilt top and the same colour is used in the bobbin. This should be a consideration when you are choosing a backing fabric. Keep the colour of your quilt and backing in mind when you buy your batting. Black batting, as well as cream and white are options. - Pieced or custom backing:
When piecing your backing keep in mind that a horizontal seam is preferred (if at all possible) for the longarm machine, as opposed to a vertical seam. Quilts are loaded from the top and it is unlikely, due to draw-up, that your seam will be centred on the finished quilt back. The position of patterns, blocks, designs or borders on the backing cannot be predicted. Pieced batting is perfectly acceptable. Simply butt the batting pieces together and sew with a zigzag stitch. (Do not overlap!)
