There are two types of right-angle weave that produce the same finished beadwork. Cross-needle weaving, or double-needle right-angle weave, is made using two needles on opposite ends of the same length of beading thread. Single-needle right-angle weave passes through the beads in alternating circular patterns.
Learning Cubic RAW: It may be easier to learn cubic right-angle weave by practicing with larger beads first.
Thread Matching: With cubic right angle weave, it's important to match the color of your thread as closely as possible to the color of your beads because a lot of thread shows.
Counting Rows: RAW can be a little tricky to count because most of the units in each row share side beads. The initial strip of units you stitch (the stitches with four beads in each unit) make up the first row. The units in each subsequent row are made with three beads in each unit. To make this less confusing, just count your rows by counting the beads that stick out of the side of the beadwork.
