To use this cardigan pattern, start by getting all the required notions. Since it's worked from the top - down, you can easily try it on as you go to adjust the length. As you knit, keep an eye on the stitch markers to ensure correct pattern placement. When it comes to care, it's best to hand - wash this merino - based cardigan in cool water to keep its shape and softness. Lay it flat to dry to prevent any stretching. And always be careful when handling the buttons to avoid losing them.
