Miyuki 1.8mm Square beads (SB18) are great for off-loom bead weaving. When woven together they create patterns and shapes that are modern and angular. Try mixing the tiny SB18s with other seed bead shapes or use them in brick, herringbone and peyote stitch. 1.8mm Square beads measure 1.8mm x 1.8mm x 1.8mm with a hole size of 1mm.
