Recently, I tried a Warm & Plush batting (made by the same co. which manufactures W & N batting). It is all cotton, slightly thicker and soft. After I washed the quilt in cold (which I use all the time), the crinkling was less than usual.
I bought a new batting put out by Quilter's Dream to try out....it is 70% cotton and 30% poly. It is designed especially for machine quilting. I haven't used it yet, but will let you know how it works out.
