Watch out for batiks if you're putting them into something that will have to be washed. They leak dye like crazy, and I always run them through the washer and dryer a couple of times and then check a (roughly) 6-inch square by hand in my bathroom sink. My sewing student recently made a small quilt out of 5-inch batik squares and I made sure we prewashed every one until the water ran clear. I would only use unwashed batiks in something that I knew would never need to be washed.
