It really doesn't matter if the fabric is Moda, Benartex, Hoffman, Kaffe..... Cotton fabrics shrink some. Lots of things determine the amount of shrinkage, the batting, the fabrics, the amount and style of quilting all play into it and each one can turn out differently. You could prewash your fabrics then spray them with sizing ( which you wash out when you prewash & is used to give them that look you seem to like) or starch. Or, you could make one, wash it & see what happens. Or, use polyester batting that doesn't shrink & heavily quilt to keep the fabric shrinkage to a minimum.
