How is painting hanging done?

In the framing workshops www.rāmji.lt, we perform painting hanging as follows.

A special knot is created that tightens when a load is applied. The more you pull this knot, the tighter it becomes.

Special "ears" and plastic-coated wire are used for this.

Everything you can purchase can be found by visiting the framing workshop Rāmji.lt. Watch the video on how a special knot is made:
