Right-angle weave

Right-Angle weave stitch, also known as RAW, is an off-loom bead weaving technique. Beads are stitched together with thread only making right angle turns, hence the name. The result is an almost fabric like piece of beadwork. Right-Angle weave can be woven with either one needle or two. With single needle right-angle weave, the thread path moves in a figure-eight pattern. For double needle right-angle weave, the threads cross each other along the center bead of each stitch as they head in opposite directions. RAW can be formed into flat pieces, tubes, or 3 dimensional figures. There are also variations on the basic stich like cubic right angle weave, or CRAW. Seed beads, fire polished beads and crystal beads are common choices in pieces using right-angle weave. Variations of Right Angle Weave also include PRAW. CRAW is usually worked in sets of four but in PRAW sets can be expanded to 5 +.
