Notes from pattern:

This set worked in baby wool has a side opening on the raglan sleeve making it easy to slip over babies (sic) head, and to finish the outfit a cute hat in the same pattern.

There is a mistake in row 2 of the original pattern. The main pattern should read as follows:

Row 1: (RS) K1, K2, P1, K1, P1, K3; rep from to end
Row 2: P1, P1, K1, P3, K1, P2; rep from to end.
Row 3: K1, P1, K1; rep from to end
Row 4: as 2nd row
Row 5: as 1st row
Row 6: P all sts
