I am making my first sweater and it calls for vertical pockets. It's a Maddy Laine Pick A Pocket 129. I have finished the pocket lining and now need to pick up the 28 stitiches from the stitch holder. My problem is, every time I pick them up, the stitches look fine at first but further up the front the stitches look very loose. The further I get the worse it looks. It becomes an obvious sore spot. How do I pick up these stitches and still have a nice and tight looking junction?
