Q. when you are turning at the end of the first row, and after you skip 3 holes to turn, after that how many holes do you skip? and do you follow this same routine for the 3rd row?
A. First, you must know (or decide) which kind of a stitch you'll be making in the next row.
If you will be making a single crochet row, then you need to chain 1 (or whatever your patterns says)
If you'll be making a double crochet row, you will need to chain 3.
I have never seen more than 3 chains at the end of a row.
