vintage two-tone baby bootie & bonnet pattern from 1970

Fast forward in time! This weeks vintage baby bootie pattern is 'only' 43 years old, a two colored bootie from 1970. Knitted from bottom to top you start with shaping the foot and finish with the patterned edge. This pattern features the 'knit 1 below' stitch which was new for me. The instep is shaped by knitting stitches together, so there is no need to pick up stitches! I guess a beginner could manage it well, if paying attention to the stitch count. As always, I tested the bootie pattern. If you like it scroll down for the pattern of a matching bonnet!
   

material & sizing:

• The original pattern uses fingering weight yarn in combination with no.10 needles (=metric 3.25) 
• As always, my test yarn is a fingering weight acrylic, which I knit with metric 3 needles. The finished bootie measures about 3.5 in (8-9 cm) along the sole.

construction:

The bootie is knitted from the bottom up. I really like how this bootie is shaped. Usually you need to pick up stitches along the instep, but here you avoid that by K2TOG's along the instep. This makes a smooth and neat edge and the knitting goes really fast. As usual, there is a seam under the sole and in the back.

the two-tone pattern:

The two colored  pattern is created  by a 'knit one below' stitch. While it sounds weird, it is easy to knit. There are two altering rows. It uses the 'knit 1 below' stitch, which only makes sense once you see it.

knit one below stitch:

The pattern is made with altering K1 and K1 below in one row and only K in the other row.

• 1. Put your needle under the stitch below the next stitch on your left needle. That way you have two loops above your needle.
• 2. Knit the two loops the same way like you should knit one

Previous to the knit-one-below rows you see purl stitches (this is different from the illustration!) and  you need  to put your needle through the hole of the V above that (see illustration below). Then you knit as if knitting a normal stitch. You'll have two strands of yarn above your needle which you slip off together.

the pattern:
The pattern is written for two sizes, from birth to two months the alternative stitch count is written between brackets. There are no print errors. Some of the instructions are written between brackets too, which works a bit confusing. As I figured out, those instructions belong to both sizes. I've written the pattern out for you until the instep decrease starts:
