I wanted this to be more fitted than the pattern showed and I also bought yarn with a lesser yardage than the recommended yarn. So I cast on 10 stitches less than pattern called for (one pattern repeat less).
Also to get gauge I used smaller than suggested needles.
I used 10mm needles to get 9sts to 4” to match pattern guage.

It is just waiting to be blocked and seamed. Eta - all done and has been worn alot! Very warm and cosy. I wear a long sleeve t shirt underneath to keep my arms warm. The short sleeves mean I can work without bulky sleeves getting in the way. Very pleased with this jumper:)
