Using this needle case is a breeze. First, decide which size needles you'll be storing. Place the needles in the appropriately labeled pockets if they match the sizes from US 2 (2.75 mm) to US 15 (10 mm). For any extra needles or special ones, use the unlabeled pockets. Put your notions like stitch markers or small tools in the zip pockets. When closing the case, just stretch the elastic over the button. As for maintenance, keep it away from sharp objects that could tear the fabric. If it gets dirty, you can gently wipe it with a damp cloth. For the new Linen Collection, be patient as it takes about four weeks to ship.
