Summarize this article:

"Overall" quilting can complement the fabric prints... for example, a fabric with a floral print could be quilted with an overall design of flower pots and spades or gardening tools.
Lay your quilt top face down on a flat surface. Lay a layer of batting atop the face down quilt. Lay your backing material atop the batting. Pin or baste the layers together, starting with a line down the center of each axis and then more basting lines parallel to the center line, spaced approximately 18 inches (45.7cm) apart. Check for wrinkles or tucks and re-baste if necessary. Place your basted quilt on a frame to stretch it smoothly as you do the actual "quilting" or stitching of the layers together with small stitches. Quilt "in the ditch" along seam lines between colors of fabric, or do an "overall" quilting design which ignores the quilt design and simply stitches over the fabric in its own pattern.
