Quilt Backing

The seam direction of your backing depends on the quilt's use.

If you are lucky enough to have a well-stocked quilt shop near you, you may be able to purchase wide quilt backing fabric and avoid having seams altogether. However, not all wide backings maintain the same quality. Check carefully before investing in this fabric. Pay special attention to "white on white" backing fabric where part of the design appears to be painted on to the fabric. Longarm needles will perforate and crumble the paint, causing tension issues, more thread breakage, and needle holes that may not recover.

When you are forced to piece fabric strips to create backing large enough for your quilt top, choose the seam direction based on the quilt's use in addition to ease of loading on your frame. Generally, horizontal backing seams are much easier to handle than vertical seams, since the seam will lay parallel to the roller instead of creating bulk as it wraps around the roller.

However, if the quilt will hang on a wall, then situating the backing fabric so that the lengthwise grain runs "top to bottom" will reduce stress on the quilt and prevent sagging and stretching. In this instance vertical seams may be more appropriate.

When you sew backing pieces together, be sure to remove the selvage edges along the seam line. You can decrease the bulk in the seam even further by pressing the seam open instead of to one side. Select a stitch length of 11-12 stitches per inch to secure the open seam better.
