For 3 necklaces, triple the components - but notice that most of these items are already sold in bulk, so 1 pack may be enough for all 3 necklaces.
Tip: 1 spool of #40-099-13-3 has 10 meters of chain, enough for more than 20 necklaces! If you are only making 1 or 2, you might prefer to buy this style by the foot. Change the last "9" to a "0" in our spooled chain stock numbers, to find the same style by the foot. (#40-090-13-3 is the 2.1mm Silver Plated Cable Chain by the foot.)

#69-123 Bench Block -- We like this combo bench block, because the rubber base helps keep the metal block from bouncing when you stamp, and the nylon portion also comes in handy sometimes. But a more basic metal bench block such as #69-236-2 is also fine!
#69-291 Basic Jewelry Tool Set
Scotch Tape (to help hold blank in place on block while stamping.)
