Consider the time spent into weaving a rug, the materials used, the size of the rug, the difficulty or intricacies of design, and the uniqueness of the item.
If hand woven, rugs can take months or years, depending on the difficulty and size of the rug. The rule of thumb here: the finer the material used – like silk or merino wool, the longer it will take to weave a rug.
Also consider if a rug is machine made or handmade. A handmade rug is a one of a kind item, which guarantees the uniqueness of your purchase.
