These slippers are pretty and elegant.
I know sometimes working with Drops' patterns is difficult, because they do not state the weight of their yarn required. All of their yarns have names and a yarn group letter, so if you don't have access to their yarns, this can be difficult. To get a better idea, go to their comparison chart, here they give you the gauge information, you can play around with your own yarn and hooks until you get the tension correct!
