Adding Pockets  

If the sweater is already knit, you really do have to make the pocket squares and then sew them on. You can line them , or you can knit the pockets on smaller needles, like you used for the ribbing, and make a border, say garter stitch at the edges so that they hold their shape. I hope this has helped? Happy knitting, Jo. Thank you Clamara@aol.com
