I expect the pattern to open up a bit after washing and blocking.
Both parts have the same size and I am going to stop here for the moment, till I get my books - as I think I need to start shaping for the sleeves now.
The yarn is lovely - if it's going to survive the washing test, I will definitely buy it again.
Now - this is a small part of my chart - just to show you that there aren't any major challenges in the pattern.
One repeat of the pattern is over 16 stitches and 30 rows - as shown at the bottom of the chart.
The background is always left blank - and every chart in this book will tell you at the bottom of the chart how to knit the blank squares (in case you can't just figure it out by looking at the associated swatch :)).
In my case, I'm purling all the blank squares (the horizontal line after the '=' sign stands for Purl) .
