anna crochets - cotton coaster

I bought some cotton yarn yesterday to make crochet garlands (see my Pinterest board on crochet garlands here!), but I decided to start with a crochet coaster instead.

It turned out a bit larger than I expected, but it is still sweet. Not sure if I will make three more for a set of four. I got the pattern for free from KRW Knitwear Studio. What do you think?
