how do you cut material for back of a quilt.
When piecing the backing of a quilt, avoid using a center seam. When a quilt is folded in half, the extra bulk of the center seam along the fold line stresses the quilt, causing the quilt top and batting to break down. Instead, cut one of the lengths of backing fabric into two long, narrow pieces. Stitch a narrow piece to each side of the full-width piece. The quilt should be loaded into the quilting frame with the seams running the same direction as the rail does (also called the belly bar) .
