This has become my new TNT pattern. I've already made two tops out of it for use under jackets and blazers. My first experience with it was bad tho. While trimming the facing around the gathered area of the neck, I guess was was in too much of a hurry and cut into the front piece. There is was -- a nasty little hole. But, it ended up being my muslin.
I was at Joann's and found this soft slinky knit in their clearance aisle.....it's great for under a black blazer.
