The selection of beads for use with a 1 mm cord depends primarily on the diameter of the bead’s hole. To ensure a proper fit, the hole size must be slightly larger than 1 mm. A bead with a hole diameter of 1.2 mm to 1.5 mm is generally recommended to allow for ease of threading and movement along the cord. Smaller hole sizes will likely cause difficulty in threading, while significantly larger holes may result in an undesirable amount of play between the bead and the cord.
Selecting appropriately sized beads is crucial for various applications, including jewelry making, crafts, and decorative projects. Using the correct bead size prevents damage to the cord and ensures the finished product is aesthetically pleasing and structurally sound. Historically, the challenge of matching beads to cords has driven innovation in bead manufacturing, leading to more precise and consistent hole sizes.
