Using this jigsaw puzzle is easy. First, spread out all the 1000 pieces on a large, flat surface. Start by sorting the edge pieces to begin forming the frame of the puzzle. Then, look for pieces with distinct colors or patterns to gradually fill in the picture. Take your time and enjoy the process. As for the precautions, make sure to keep the pieces away from small children who might swallow them. Also, avoid placing the puzzle in a humid environment to prevent the cardboard from warping. For maintenance, after you've completed the puzzle, you can use a puzzle glue to preserve it. Just follow the glue's instructions for best results. You can then hang it on the wall or store it flat in a protective case.
