The star stitch is in multiples of two +3So I would chain 103 to start
Fpr my Lapghan/coverlette.
I started with ch 163, on the second row I completed 1 row of single crochet.
I used a 4.5mm (UK) hook
Pattern is in US terms.
And I used several ends and colors of Aran Yarn.
This is a free Crochet pattern that peaked my interest in using the Star Stitch It is for a Baby Set, hat booties, blanket and cardigan (I woudl say you need to have a good understanding of crochet to undertake this vintage pattern, however using todays yarns and colors very much a todays wearable for baby.
