I have used it in plenty of bed quilts. Just understand, McTavishing was developed as a back fill to make other quilting motifs pop. So use it accordingly. Sparingly to make a motif pop. Additionally the batting makes more of a difference in how stiff a quilt gets when laying down a lot of thread. Use wool batting with a very fine thread like silk or invisifil and you won't get any stiffness. In all of these below, except the calla lilly, I used double batting and polyester thread. The Calla had 80/20 batt. Here are pics of examples where and how I have used it in bed quilts.
