Hi,
Very new to knitting, I think I’ve worked out how to cast on at the beginning of a row. However, I’m confused at the following instructions. ‘Cast on 5 sts at the beginning of the next 6 rows’ - do I cast on a row then knit then add another until I’ve done 6?
The second part of the instruction throws me off further by saying ‘66 sts’.
Any help would be greatly appreciated thank you in advance!

What is the name of your pattern and designer?
Cast on 5sts at the beginning of the row (row 1) then knit or work in pattern to the end of row. Turn, cast on 5sts at the begining of row 2 and then work to the end of the row. Now repeat those 2 rows twice more.
You will have cast on 30 new sts. Does that make sense with the stitch count before these cast ons? It should be 36sts before the cast ons and 66sts after these cast on rows are completed
