I think it would be very cute for icing! I've used it on wall hangings, but the LQS has a jacket made with it that is lovely. The last wall hanging I did used texture magic for the tree trunk. We sewed "grain lines" for the trunk using TM, even knot holes. When it shrank it was amazingly realistic! Just remember to use a nice wide satin stitch to sew it down (if you're not piecing it) since it's a bit hard to control at the edges.
