Using these DIY 3D cosmos beetle wall decorations is a breeze. First, find the assembly instructions inside the packaging and follow them step - by - step to build your beetles. Once assembled, you can hang them on the wall as eye - catching wall art. Or, if you prefer, place them on your table to create a unique display. When handling the beetles, be gentle to avoid any parts breaking. Keep them away from excessive moisture and direct sunlight to prevent color fading. If they get dirty, you can use a soft, dry cloth to gently wipe them clean.
