How to make a loom at home?

Could you elaborate on the steps involved in crafting a loom at home, please? I'm interested in understanding the necessary materials, tools, and techniques required to successfully build one. Could you perhaps start by outlining the basic components of a loom, such as the warp beam, cloth beam, heddles, and reeds? Additionally, I'd appreciate any advice on how to select suitable materials for durability and functionality. Are there any specific design considerations I should take into account, such as the loom's size or intended use? I'm also curious about any safety measures I should follow during the construction process. Thank you for your guidance in this matter.
