How do you make the knot at the back of a necklace with a red cord that you can pull on each other to adjust the size of the collar? I've seen the picture given by the pro, said it is still confusing it ~ please solve! The person who asked the question has to read Oh, that even though the drawing is relatively ugly, but not difficult Oh.

This way:

1. Leave the pendant in the center of the rope. Take a clip or tie a good knot first.

2, each end of the "construction", take the head of one of the A, in the other B knot, specifically, take A around the B twice, and then A through the two circles. In this way, B, the rope can move, the range don't go over, or it will draw A out.

3. Now it's time to take the head of B, the rope, and do it again on A in the same way as you just did.

4, adjust the size and fix it, burn it with a lighter, and you're done.

Suggestions:

1, first take a thicker rope to practice, familiar with it, you will find it very simple. When I practiced, I used the kind of rope that is used to carry a paper bag, like a shoelace, with plastic clamping at both ends.

2, if you really do not have the patience, go to the jewelry store to ask the clerk to help you braid, pay attention to observe Oh, learned next time you do not have to spend money.
