I'M IN LOVE. Despite the styling with the white jeans (King Cole's favourite design choice), this lace pattern is absolutely gorgeous. It's not as hard as it looks, either, especially with the drop shoulder so you're not having to faff about with raglan decreases. I love the sleeves, too!
This has been written in King Cole Merino Blend DK, but I think it'd look fabulous in the King Cole Subtle Drifter DK, with its gorgeous heathered shades (especially the green). You'll need 3.75mm and 4mm needles along with some buttons for the cardigan.
