In the table above are noted the different diameters of the beads used in many of the specialist patterns introduced by Howard Croston and Lubos Roza. The letter appears after the hook size, for example 14d to denote the size of the bead. If no letters appear and the pattern is offered in more than one size, the bead size will be constant throughout the pattern.
