They are made from a naturally growing source and will have variations from handle to handle.† Each will have unique patterns and coloration.† To us, that variation is part of the beauty and appeal, and can really add to your work.
Hold your handle up to your pot and notice how much larger or smaller the handle is than the distance between the lugs. This will give you a sense of how much the handle will need to adjust to the size of you pot. (If it is more than 1/2" larger or smaller, you may want to consider getting a more closely sized handle.)
Pull the woven retaining ring up on one side, past the narrowing end of the handle loop.
Dip that end of the handle into boiling water for about 5 seconds.This will temporally make the handle more pliable in that area.
Put the loop around the lug on the pot
Slide the woven retaining ring down into place. (One side complete!)
Pull the woven retaining ring up on the remaining side, past the narrowing end of the handle loop.
Dip that end of the handle into boiling water for about 5 seconds.
Put the loop around the lug on the pot. (Note: It will be harder to do this time because you cannot maneuver the handle as freely as you could on the other side. Don't panic, and if you find the handle is loosing it's pliability, dip it into the boiling water again.)
Once looped, slide the woven retaining ring down into place. (Complete!)
