Curtain hooks are the little things that are that
Made of many materials, the most common are plastic and metal. Some manufacturers do not pay much attention to the quality of the metal, because they think the hook is hidden and nobody will see if it is good or not. In this scenario, plastic hooks are the best solution. They never come change colors and they are difficult to break, they also do the job just like the metal. The best metal used to make hooks is stainless steel, as it hardly rusts or changes colors; It also has high endurance compared to other metals.
There are no many patterns for curtain hooks, and everything depends on the ribsthey will be attached to. The simplest form of it is a curved shape that goes into thick threads on the belt. There is another form of them that looks like a fork with a small curved piece to enter the rings. Both forms are large and they do the same job, the only difference between them is the band they are inserted in. So do not buy hooks unless you know what type of tape is on your curtain.
Hooks Vs. Rings
Many people confuse the rings with hooks, for them we say it's easy to distinguish. Curtain hooks are the ones that are stuck in the curtain itself, but the rings are the ones thereat the pole goes through. They end each other because the curtain cannot be hung without both being present.
