Using the della Q Tri - Fold Circular Needle Case is a breeze. First, open the case by undoing the elastic and button closure. Sort your knitting needles by size and place them in the labeled pockets according to their US sizes. For extra needles or special ones, use the unlabeled pockets. Put small notions like stitch markers or measuring tapes in the zip pockets. When closing the case, just stretch the elastic over the button. As for maintenance, keep it in a dry place away from direct sunlight to prevent the linen fabric from fading. If it gets dirty, you can gently wipe it with a damp cloth. Remember, the new Linen Collection colors will take about four weeks to ship, so be patient!
