| Hand-Hooked – Rugs made in a manner similar to that of hand-tufted rugs, except that the pile is left looped rather than cut. Canvas backing is spread on a frame and a hooking implement is then used to pull the yarn through the fabric. Latex glue is then applied to the back of the rug to hold the loops in place. Another layer of cloth is added to the back of the rug and the rug is then finished by turning under the ends. | |
| Hand-Knotted Rugs – The most expensive and longest to make, hand-knotted rugs are traditionally made with wool or silk.

Jute yarns are strong and often used as warps in knotted rugs. | |
| Kashmir– Silk or mercerized cotton carpets from the Islamic region of India. Kashmir rugs are woven with Persian knots and have coloration and ornate patterns unique to India. | |
| Kelim (Kilim)– The most well known group of flat-woven rugs. No knots are used in creating kelims. Simply, the weft strands are woven (passed) through the warp strands. | |
| Knotted Rugs– The knotted carpet refers to a particular decorative and functional textile made by hand on a horizontal or vertical loom using the technique of knotting. This weaving style involves wrapping tufts of wool or pile around the warps. They wool or pile is then tied around each individual warp strand to erect the pile at a 90 degree angle to the floor. | |
| Lattice– A design used in an all-over layout. Lattices consist of an arch or two connected, or rectangles with usually some floral motif inside them. In classic Persian rugs, lattices are curvilinear and consist of arches. The new versions are more geometric and consist of diamonds and hexagons. | |

| Weave– The technique used in weaving. There are two major weaving techniques, pile weave and flat weave. | |
| Wool– Fiber acquired from the hair of sheep, goats and a selection of other domesticated animals, including alpacas and twisted into yarn for weaving. Wool is the most frequently used pile material in handmade rugs. Wool straight off a sheep is highly water-resistant. Wool retains heat better than most fabrics when wet. Australia and New Zealand are leading producers of wool. | |
| Wool Sisal– Wool sisal-look rugs are popular alternatives to real sisal (coir and sea grass). | |
| Worsted– Before wool is spun into yarn, it is combed, and then worsted to improve its quality by leaving only the longer pieces of fiber for final spinning. It is used for more intricate patterns. | |
| Woven Carpets– Carpet made on a weaving loom where backing threads and pile are woven at the same time, creating strong anchors for the tufts. |
