Miyuki Delica #11
Delicas are preferred for peyote stitch, brick stitch, and weaving on looms because their cylinder shape gives the finished piece a flat surface that maximizes any design or pattern. Their exceptional uniformity of size and shape creates tiny rectangles which lock together to present an unbroken surface. Bead artists have used them to create detailed portraits and sculptures with each bead acting as a single pixel of colour.
11/0 Delica Beads (DB) are our most popular size of cylinder beads and are available in over 200 colours. Delicas are ideal for peyote stitch, brick stitch, square stitch, and herringbone stitch or strung as-is for a more delicate look. 11/0 Delica beads can be either smooth or six-sided (hex cut), and measure 1.6mm x 1.5mm with a hole size of .8mm. The count is approximately 200 beads per gram.
