In knitting, rows are worked in alternating directions, with one row worked from right to left (the “RS” or “right side”) and the next row worked from left to right (the “WS” or “wrong side”). It’s important to be able to tell the difference between RS and WS rows in order to produce a consistent and even fabric. There are a few key ways to do this, and they vary depending on the type of stitch you are using.
One of the most common ways to tell the difference between RS and WS rows is by looking at the way the stitches are formed. On a RS row, the stitches will be formed with a “V” shape, while on a WS row, the stitches will be formed with a “^” shape. This is because on a RS row, the yarn is passed over the needle from back to front, and on a WS row, the yarn is passed over the needle from front to back.
