The 10/0 Delica bead (DBM) is the second largest of the four sizes of Delica bead, and is available in over a hundred and fifty colors and finishes. Delicas are precisely cut glass cylinder beads with a rounded surface and two flat ends. The 1mm hole size is large in proportion to the bead size, enabling multiple passes with a needle and thread in stitching projects. In bead weaving, rows and columns of Delicas uniformly line up to create a flat surface that highlights pattern work.
