I finished the second i-cord on my Starry Night cardigan! It still needs blocking and buttons but it's wearable at this stage.
I knit the buttonhole front first with the 3.25mm in case I needed to make some modifications but it worked well. Around the neck I used a 2.5mm needle again as I had with the lime i-cord. This really helped tighten up the neck rather than putting in more k2togs. Then came the home stretch - the left front - and it was done!
