King Cole always excel with their lace patterns, and this one is no different. Raglan shaping always makes garments fit beautifully and with the slightly-oversized nature of the jumper's body and sleeves, you've got a great fitting garment that's still incredibly comfortable. If you like the jumper's all-over lace body but you'd like the lace panel of the cardigans sleeves, that would be an easy swapover, I think. We can have a chat about it if you'd like!
This has been written in King Cole Cottonsoft DK, a 100% cotton yarn that will add to the airiness of this summer pattern. But, if you'd like to adapt it to warmer weather, consider the King Cole Majestic DK!
