Pattern Book Peter Pan 355

Here are some answers for the use of repeats using brackets In regards to the Peter Pan book 355:(  )  = instructions are given for the smallest chest/bust size with larger sizes given in round brackets.
[  ]  = Work instructions within brackets as many times as directed
*   =  Repeat instructions following the asterisk as directed
**   ** = Repeat instructions between the ** and ** as directed

Example:
[p1, k1] twice
*p1, k1; repeat from * once more
The last two lines mean the same thing it is just that the 2nd one is twice as long and therefore also takes more time to read
