I've copied a part of the pattern, and inserted my notes by the *'s. I hope this helps!
Cast on 5 sts.
Knit 6 rows.
Next Row: Increase in 2nd stitch of each row until you have 22 stitches on the needle.
** I would interpret this to mean that you increase one stitch per row until you have 22 total. This means it will take you 16 rows of knitting to work up to 22 stitches (if I can add!) **
Next Row: Increase in each stitch to 44 sts.
** I would interpret this to mean that once you have 22 stitches on your needle, you will need to increase in every stitch for one row of knitting. You would do this by kntting in the front and back of each stitch.
So...you will have six rows of 5 stitches knitted, then you will slowly increase -- one stitch per row -- until you have 22, and then you will make a big increase -- one increase per stitch in one row -- to 44.
Someone please correct me if I'm wrong!!
