This is offered to you so that you can learn the way to figure out short rowing.
Once you learn this formula you will be able to do hats shawls or Afghans.
CIRCULAR SHAW OR AFGHAN
According to Alles Hutchenson:
There is probably more advanced math in than in anything else you have done.
The entire piece is done by short rows (partial knitting).
You will need only one measurement-how wide do you want the finish piece to be.
For example we will use 2.25 stitches and 4 rows = 1 inch. The diameter will be 40 inches. With
10 panels. You will substitute your own stitches and rows, and how many panels you want, but
follow the same principle.
(1) Find the circumference of the circle.
FORMULA: to find the diameter of a circle, multiply the circumference of a circle,
40 inch circle.
40 x 3.14 (pi) = 125.6 (six is larger then 5 so the answer is 126)
(2) Change inches to rows.
126 x 4 rows per inch = 504 rows around the edge.
(3) Decide how many panels you want:
10 panels .....504 rows divided by 10 panels = 50.4 (4 is less then 5 so the answer is
(4) Find the radius of circle and change inches to stitches.
Radius = ½ the diameter of the circle.
40 inches divided by 2 = 20
20 x 2 stitches per inch = 40 stitches, (this is what you will cast on).
(5) Shape this by short rows so that it will become a pie shaped piece.
Each section will be short rowed down to the next to the last group. The last group `
will not be worked. Then 2 rows are knitted over all needles.
Since short rows are done only on alternate rows, divide the number of rows by 2.
50 rows divided by 2 = 25 rows.
(6) Distribute the stitches evenly over these rows.
You have 40 stitches to shape in 25 rows.
Since the answer you want is stitches, divide rows into stitches.
25 rows divided into 50 = 2 stitches to short row.
25 rows / 50 stitches
Therefore you will short row 2 stitches every other row
