Please clear up some confusion about pattern

Hi all,
Okay I have a question. I am checking out some patterns from the book 200 Ripple Stitch patterns. I love this book! Anyway almost all of the patterns read something like this:

“CO multiples of 18 plus 1”

What I take it to mean is cast on a multiple of 18 then add one more stitch at the end…
18 (3x)=54+1=55

Is this right? I want to start practicing some of the stitches so when I start my next afghan I can cast on the appropriate amount of stitches.

Thanks in advance for the help. :hug:

Yes, you’re absolutely right.

Wow, thanks so much for the quick response :slight_smile:
