The pattern is written for three different sizes, using 5, 7 or 9 hanks of Blue Sky's Metalico (baby alpaca and silk) yarn. The sample is shown in the largest size.
The pattern includes a chart and written instructions. I recommend following the written instructions and using the chart as a guideline for how the stitches relate to each other.
This was one of those finished projects that I was sad to send away. It's definitely something I'd love to have for myself.
