Some patterns that use cylinder beads refer to the manufacturer's reference number of the bead color. These patterns will specify the reference number of either the Delica or Toho cylinder bead color that is to be used.
Before you start your project, sort your beads, either on your work tray, bead mat or bead dish. You can use small pieces of paper with the numbers written on them, or you can use sticky notes to help you remember which bead is which.
