The Baby Surprise Jacket was designed by Elizabeth Zimmermann in 1968 and remains a popular baby garment to this day. It is an excellent pattern for making use of oddments of yarn or self striping yarns with long color repeats, but looks equally nice knit in a single color with a contrasting button band.

The jacket is knit in a single piece with just two seams that run across the shoulders and down the length of the sleeves. It includes extra ease across the back of the garment to fit well over a nappy (diaper).

Commonly referred to as the “BSJ”, the Baby Surprise Jacket is “a very entertaining piece of knitted engineering”
