The Nervous Prayer Beads, also known as the Kombola, is a Greek toy for anxious people that is used to relieve stress and for general enjoyment. You can make them yourself with just a few inexpensive components. To get started, see Step 1.
Steps

1 Take the beads.
Traditionally, a rosary for nerves contains an odd number of beads, usually one bead more than the number multiplied by four, for example, 5, 9, 13, etc. In addition, you will need one "main" bead, which is usually larger than the others. Natural materials such as stone, amber and wood are believed to be more enjoyable to work with, but you can use whatever kind of bead you like best.

2 Take or make a brush (optional).

3 Cut the rope.
Usually the length of a Nerve Bead loop is two girths of the hand, so cut the thread so that it is at least 4 girths of the hand, plus leave enough space to attach the 'main' bead and tassel.

4 Pass the smaller beads through the thread.

5 Pass both ends of the thread through the large “top” bead.

6 Tie a knot to keep the beads from falling off the string.
A simple knot will work here if the thread diameter is close to the inside diameter of the bead hole. If your thread is significantly thinner compared to the holes in the beads, you may need to make a larger knot.

7 Attach a brush (optional).

8 Fingering with your own hand-made "rosary for the nervous" to relieve stress!
Advice
- Use a strong, smooth thread that will easily thread the beads.
- Use beads with smooth edges to avoid discomfort or cuts when working with them.
