This pattern can be worked in any size with any weight yarn; just make sure you start with an odd number of Ch (e.g. multiples of 2+1). I recommend making a gauge swatch first if you want it to come out a specific size.

Pattern abbreviations:

ch – chain
sc – single crochet
dc – double crochet
st – stitch
