This beautiful piece was knit with white sateen yarn.
You start knitting from arms. You start knitting 15 stitches, then every 6 rows, at a point on down side of the arm, you increase. When you come to the body part, you knit 35 stitches on the knitting needle. When you complete the body width, you cast off 35 stitches, the second arm, as parallel to the other arm, every 6 rows, you continue by decreasing.
After knitting the other side the same way, you combine by needling down sides of the arms and the body part. You combine the upper sides of arms by crocheting chain stitches. When you finish all these, the blouse is ready 🙂
