I need motivation to start machine knitting.   I get bored making the same shapes.  The only option I have is to use my sewing skills and create a pattern the old fashion way.  The video below clearly explains the process :

How to resize the pattern the next question?  Again, more research!  First we need to know the standard sizes found here!  Also,  I’ve  learned the following from Ellie Maclin:

To convert a small pattern to a larger size  garment figure out the number of stitches at the neck and chest of the smaller garment.  If the smaller garment’s neck measures 52 stitches and the chest 112 stitches calculate the percentage (52/112 is 46%). The neck on the larger garment is 46% of the chest/diameter. To find the neck stitches for the larger sweater do a swatch and calculate how many stitches per inch.  Next, calculate chest diameter such as 216 stitches times .46 to get total stitches for the neck. The result is 99 stitches then divide by 3 is 33 stitches for center neck and 33 stitches for each shoulder.

The article also stated that the rule of thumb for sleeves on a sweater is 20% of the cuff stitch diameter and 33.3 % of the upper arm stitch diameter. Repeat steps above to figure out other parts of the sweater. The next question is are there other rules of thumb?  Yes, according to the golden rule,  arms stretched out is the height of the body, eight times the length of your head equals the length of your body, the distance from your wrist to your elbow represents foot size.

Chart cast-on stitches and length in rows on the pattern and note increases and decreases.   Please comment.
