Generally, 20 stitches are sewn first, and then the stitches are replenished according to the specific size. In fact, wool is generally sized according to the number of stitches, which can be roughly divided into three types according to the thickness: one is high thick thread: 7-8 stitches with a width of about 3.3 cm (1 inch) and a length of about 3.3cm 8- 10 stitches, and the other is medium thick thread with 9 stitches 10 stitches. When knitting patterns with these three kinds of threads, there is generally an error of 1-2 stitches. Therefore, the number of stitches should be appropriately increased or decreased according to the density of the pattern. There is also a more intuitive and accurate calculation method, that is, the test method: starting with 20 stitches, weave 3.3 cm according to the pattern you need, then measure the specific size with a ruler, and then calculate the size of the sweater based on this.
