Welcome!
Rows 1-12 have set up the placement of the various patterns: ridge stitch, cable stitch and bobble panel. Continue those patterns as set in the places where it says “pattern 18”. (Five ridge + 4 cable + 5 bobble + 4 cable will give you 18sts.)
A similar continuation of the pattern panels will be true where the pattern indicates “pattern 22”.

You should be able to look at the previous rows and follow the stitch patterns as set there.

Thanks so much. That makes sense x
