In order to get the right gauge I had to use a 5mm hook and worked 18 rows in total which gave me 9 rows of stars. So long as your squares are all the same size after blocking it really doesn't matter that much. We all crochet to different tensions. We are human, not robots ;-)
I really love this square! It was a new stitch for me to learn (always a good thing) and I can see me using it again.
Just a quick post tonight as have lots going on at the moment.
Next time WILL be the Monsoon Stole reveal....honestly!
Til then x
