Embroidery depends on what material it is made of, such as silk thread for edge embroidery. As long as you pay attention to moisture, don't get wet.

It is usually packed in wooden cases, depending on how you arrange it. Pay attention to dust prevention and cover it with plexiglass.

You don't have to do anything deliberately, as long as it's not dirty, and the painting with better workmanship has no flaws, so you don't have to deal with the thread separately.
