The industry is now a highly specialized one with several different manufacturing processes.

Cloth and paper
 
Paper flowersFive main processes may be distinguished:

The first step consists of putting the fabric in gelatine in order to stiffen it.
The second consists of cutting up the various fabrics and materials employed into shapes suitable for forming the leaves, petals, etc.; this may be done with scissors, but more often with stamps that can cut through a dozen or more thicknesses at one blow.
The veins of the leaves are next impressed by means of a die, and the petals are given their natural rounded forms by goffering irons of various shapes.
The next step is to assemble the petals and other parts of the flower, which is built up from the center outwards;
The fifth is to mount the flower on a stalk of brass or iron wire wrapped with suitably colored material, and to add the leaves to complete the spray.
Paper and cloth flowers are also made with origami.

Soap
There are two methods:

Carved: A bar with layered colored soap is mounted in a lathe, and circular grooves are chiseled into it. The finished flower is symmetric and regular, but the flowers are not identical and can be called handmade.
Molded: An oil-less soap milled to a powder is mixed with water, and the paste is used as a modelling material. Leaf and petal textures are stamped or rolled onto the soap. This is an expensive, labour-intensive process.

Clay
Clay flowers are made of powdered clay mixed with water and coloring. Even though somewhat less realistic than the plastic ones, stylized and good taste clay flowers can be a great addition to any environment.

Plastic
Injection moulding is used for mass manufacture of plastic flowers. Plastic is injected into a preformed metal die.
