I spray basted a king+ (it kept getting bigger as I went!) once.... on the driveway, on a blue tarp from Home Depot. Sprayed a section at a time..... Walked on it with sock feet to push it all together. Worked fabulously and I've never used any other basting method since. I'm 6' tall and "fluffy, not fat" and getting down on the floor for a couple hours just doesn't appeal to me!
