That's what it says on the pattern envelope. I have quite a few lovely knits in my stash but have not had the courage to sew them as I don't have much experience with knits. After reading several blog posts on McCalls 5974 I decided to try it with some inexpensive knit I bought on sale. Don't know what I was afraid of. It was pretty easy to sew and with the help of the serger made up really fast.
