1 First, clean the necklace with a dyed cloth to avoid stains and oil stains. Secondly, we need to pour out the dust or dirt in the jewelry box. If you don't have a ready-made jewelry box at home, you can use cardboard to process it properly and cut it into the size of the jewelry box, then fix two rubber bands on the upper and lower sides of the cardboard respectively, and then fix the necklace through the rubber bands. 3. Put the box upright, then nail two nails on the box and scrape the necklace on the line, which can also prevent the necklaces from winding together and also have the effect of display. 4. You can also use straws that are common in life to help with placement. The method is to cut the straw into the same length as the necklace, then put the necklace into the straw, and then fix the two ends at the two ends of the straw, so as not to knot.
