1. Don't use poly batting. The spray will stick for a little while, then disappear. I always use either cotton or 80/20 cotton/poly.
2. Layer your quilt (backing/batting/top). Fold back half of the top and lightly spray only on the batting. Bring the top back down and smooth out. Repeat for the other side of the top. To spray the backing you can either repeat these steps, folding back the batting and top, or flip the quilt, depending on the size.
3. To keep overspray down, lightly spray the center first then go to the edges and direct your spray into the center as you spray from the edge to the area in the center you have already sprayed.
4. Smooth the layers with your hands. On larger quilts I have found a yardstick works well. Just lay it over your quilt, tilt it on its side and sweep it from the center to the edges.
5. I will generally start quilting by using my walking foot to sew along at least one border. This keeps everything stable and I can remove the stitching if I find my backing is too loose after I've quilted the center. However, my last quilt I took a big chance and quilted and bound the border first so I could cut away all that extra material and get enough room to quilt the middle. Here's the result.
