Coil 1: coil a, hook 14 long needle in the coil (the vertical needle of the 3-lock needle is counted as 1 needle, and finally it is pulled out with the vertical needle, so it is pulled out at the back).
Cycle 2: Hook 2 long needles, each with 28 needles.
The third lap: change to line B, a group of 2 needles (1 needle hook 2 long needles, second needle hook 1 long needles, 8 lock dog teeth needles).
Cycle 4: change the A line. 3-needle long needle, the first 2 hooks 1, the third hook 2 long and 8 locked dog teeth needle. From the back of the upper dog tooth ring to the next group, three long needles are also hooked into a dog tooth needle with 4 long and 8 locks, and so on.
The fifth lap: change the B thread, that is, hook the dog tooth needle with a 2-long 8-lock needle at the last 1 needle, and change it from 4 stitches to 5 stitches.
Turn 6: change color A, and finally 1 needle hook is 2 long, 8 locks dog teeth needles, from 5 stitches to 6 stitches. Let's hook the dog's teeth in turn with crochet.
Later, we will change the thread every turn according to the above rules, and hook the dog tooth needle on the last 1 needle of each group in turn with 2 long and 8 locking needles until it reaches the desired size (the dog tooth ring should also be pulled out in turn).
On the last lap, the B line was still used. First, draw the 1 needle to the left long needle, and hook the 1 short needle at the lower 1 needle (that is, the middle long needle) (then hook eight long needles directly at the left needle locking gap, and hook the short needle at the middle 1 needle of the next long needle). Repeat the tick method in brackets and tick the whole circle. In this way, a beautiful two-color striped round pad is completed. The diameter of the demonstration product is about 48cm, and the size can be decided at will.
