Unable to find suitable display pots for my collection of cacti and succulents, I decided to make my own. I crafted moulds using a variety of materials, including card and plastic, or using cheap plastic pots with interesting shapes and textures.  For the casting material I experimented with different types of sand mixed with cement and other stuff.  Here are some examples - ranging from rough cast items that look as if they have been carved from stone, to smooth geometric shapes.  I can make other sizes and shapes to order
