I'm not an expert on this, but this is what I've read. Quilters Dream is needle punched, so you want your needle to be going in the same direction as when it was processed. Technically, that means the part that has dimples or indentations goes up against the quilt top. Or you can stick a needle through each side; the side where the needle goes in more easily would be the side that goes up. However it probably won't matter at all, especially with the very low loft request batting.
