Please help understanding bonnet pattern. Trouble figuring out how many stitches just before shaping the crown.

Hi and welcome!
I think this is the pattern. Look at the number of stitches cast on and whether there are any decreases or increases before the crown shaping that would change that number. That should give you an idea of the number of sts you should have. Also, can you give us the row diretions for the first decrease row to shape the crown? That may help too.
