This is an original Magic Pattern for a slip on jumper. Magic Patterns were first created by Mary Brooks Picken and published by the institute she founded, the Woman’s Institute of Domestic Arts & Sciences, in their magazines Inspiration and Fashion Service. We have chosen to keep the authenticity of this original pattern intact and therefore have not changed instructions based on modern design. This pattern does not contain pattern pieces; a cutting diagram for pattern pieces is included in assembly instructions. Happy Sewing!
