From the pattern:

“Basic shaped cardigan for Mattel’s Barbie. It has an easy raglan sleeve design with instructions for long as well as short sleeves. The cardigan’s front bands are worked in a seed stitch pattern while you knit the body so there is no need to pick up stitches at the end.

“Rating: #2 – Intermediate. Although you only need to know how to knit and purl, you must be able to read instructions, and increase and decrease stitches. Uses very fine lace weight (2-ply) yarn on size 5/0 (00000 or 1 mm) needles with a gauge 19 stitches per inch and 26 rows per inch.”
