Preparing your quilt will result in more precise and even longarm quilting
Backing and Batting
The backing and batting should be 4" wider and longer on each side than the quilt top. Press top and back
Seams
Backing seams should be pressed open for a flat finish. On the quilt top, light colored fabrics should be pressed toward dark fabrics when possible. Remove salvages. This prevents puckering
Square up the Backing
Properly square up the quilt back. Charge for this service if not squared
Prep layers
Do not attach top, batting and backing. They must be separate when loaded onto longarm
