In sweater design, a set-in sleeve construction means that the armhole shaping begins just a bit below the actual armhole of the body and curves along the natural edge of your shoulder. Sweaters with set-in sleeves can be worked as one piece, or in pieces and seamed like today's free pattern, Rosabella. I always find seaming a set-in sleeve to be daunting at first, but after watching our how-to video, I can finish my sweater with confidence!
Worked in pieces and seamed, Rosabella has a classic set-in sleeve construction and features feminine floral textures and lace.
