The basic frame used for weaving. Two horizontal beams are used to tie the vertical warps and hold them tightly in place. Looms can be either horizontal or vertical. Horizontal looms are small, used for nomadic weavings and can be folded in order to be transported on an animal such as a donkey, horse or camel. Vertical looms are used for weavings of large rugs and are stationary. Three or more people can sit side by side and work simultaneously.
