When knitting sweaters, making sure the stripes on the sleeves and body align perfectly is a real challenge. It all comes down to the type of sleeves you're working with. For raglan and set-in sleeves, the key is to match those stripes with the underarm bind off.
It's like cracking a code that gives your sweater that polished, put-together look. The attention to detail can make or break your design.
