I finally finished this, it took me ages to get around to doing 1 cuff! I think that as I didn’t put bust darts in it, my chest is pulling the border a bit. I thought bust darts would look odd if I chose to wear the cardigan unbuttoned. Maybe I should have made the border a bit wider, but I couldn’t face redoing it again! I think it’s also rolling slightly so maybe I could block it a little?
Anyhow I have moaned extensively on it on my Ravelry projects page
