This is a different way to start stitching, the often never updated lockstitching or backstitching. On some high-end new machines they do the starting stitching with the machines help, but with older machines and less expensive machines, this tip may help a few people.
Instead of starting near the raw edge of the fabric, I start about 1/2 inch in, well within the standard 5/8″ seam allowance, and then I begin with backstitching a few stitches then go forward.
Helps with not distorting the raw edge, and the start point is further in the fabric less likely to undo, then when closer to the edge.
I learned this from an old sewing book from the library when I was about 8 yrs old.
