Remember to allow for the length of your clasp. If you use
spacer beads or mix sizes this chart may not be accurate.
If the size bead you are working with is not on our chart here is the formula
for calculating:
1" equals 25.4mm
Measure the bead you are working with. Take the length of your project and
multiply the number of inches by 25.4mm, take that number and divide by the size
of the bead.
