A customer showed us this pattern because she crocheted a number of them, and we fell in love with it! Her preferred yarn for this project is Vintage DK. However, we wanted a sample for one of our newer yarns, Line -- a DK weight linen/cotton blend. We love the look and it's always nice to have different fiber choices. Line (pronounced Leena) is nicely priced too. We've machine washed this yarn and it holds up nicely. That said, it would be perfect for an adult top too, whether casual or fancy.
