Here is the swatch I did for the Japanese Cable Vest KAL on Ravelry.
This is my second attempt. I had a hard time with the chart for the top diamond because one of the symbols used wasn't in either of the Japanase symbol books I have. Luckily, I was able to figure it out and this swatch looks much better.
I'm using Lion Brand Wool Ease on size 10 1/2 needles. The yarn is little more of an oatmeal color then this picture shows.
Next up: converting the pattern to my size.
