Some help please

Learning Blender and created a textured cloth over a cube and it looks ok with wrinkles and all, but when I join them the cloth pops back into a plane. Can’t I make them one object?

Any advice would be greatly appreciated.

Convert the cloth object to a mesh object if you are not planning to animate the cloth, otherwise you will need to “pin” the cloth vertices to the vertices you would like to stay, btw I think this is not the right place to post about help this os for Blender and VG discussions not support I’m guessing here.
