I have heard that slinky was hard to sew on but I love the fabric for tank tops or shells. I have a number of them from Chico's but they are getting expensive so decided to try to make my own. These fabrics came from the Michael Levine outlet store in LA where you purchase fabric by the pound. It wasn't that hard to sew on and now I have three new tank tops to go under my blazers. The pattern I used was Silhouette Patterns #500 Tank Top/Pleated Top.
