WORK DESCRIPTION 

Back and front details Knit as one piece, starting with the booties. For the left bootie
with a single thread on needles No. 3.5 cast on 37 sts and knit 1 row of purl on the wrong side. Mark the 2nd and 20th sts and knit in stockinette stitch, making 3 yarn overs on both sides of the marked sts every 2nd row = 49 sts. Then knit 6 rows of purl fabric without increases, 2 rows of stockinette stitch, and 6 rows of purl fabric. Place the first 23 sts and the last 15 sts on a holder and knit the remaining 11 sts in garter stitch, knitting the last st of the toe with the first st from the holder 7 times. Resume knitting all 35 sts and knit 6 rows in ribbing 1x1. For the leg, continue knitting on needles No. 4 with double thread in garter stitch. After 17 cm, set the work aside. Knit the right bootie the same way, marking the 18th and 36th sts for increases. For the toe, leave the first 15 sts and the last 23 sts on a holder. Knit the leg the same way. On the right side of the work, combine the sts as follows: cast on 10 sts, place 35 sts of the right leg on hold, cast on 10 sts, place 35 sts of the left leg on hold and cast on 10 sts = 100 sts. Continue knitting in garter stitch. After 20 cm from the beginning of the crotch line, divide the work as follows: 27 sts - right front part, 46 sts - back, and 27 sts - left front part. Continue knitting the 27 sts of the right front part, decreasing for the armhole every 2nd row 14 times by 1 st. At the same time, after 7 cm from the beginning of the armhole, close 9 sts for the neck, 2 sts every 2nd row and 2 times by 1 st. Knit the left front part symmetrically. Resume knitting 46 sts of the back, decreasing for the armholes on both sides every 2nd row 14 times by 1 st. Close the remaining 18 sts and finish knitting at a distance of 47 cm from the booties.
