How long should I make the strands for a multi-strand necklace to finish with a 16 inch twisted necklace? I will be working with 3 or 5 strands.
A good formula to follow is to double the length of the intended finished necklace (32 inches in the case of a 16-inch necklace) and add 4 inches to that length (which results in 36 inches for a 16-inch necklace) when making a twisted necklace. The diameter of the beads used makes a difference, as does the number of strands used. If you are using beads with a small diameter, such as seed beads or triangle beads, you need less extra length; using larger diameter beads necessitates a longer length.
Secure the ends of the stringing material with a Bead Stopper™ then measure the necklace twisted to ensure a good fit before finishing the ends.
