The answer is a bowline or sheet bend (same knot). They show how to do it with pictures.

It depends what material you're tying. For twine, sure; if you're hanging a 30 kg artwork you probably want to use steel wire, and pretty much any kind of knot is unsuitable here.

  Rubbish. Stuff like e.g. boats in the multi-tonne weight class are secured by tying knots every day. Spearfishers. Mountain climbers. I could go on. Get some 2 mm Dyneema rope, which has an average breaking strength of 300 kg, run it through some D-rings and tie it with an Alpine Butterfly. You will be able to do pullups off that artwork if you want.

Oil rigs are towed to location using steel cables. Steel wire rope is substantially stronger for its weight and for it size but generally harder to work with than plastic things of similar capacity. Both materials can hang pictures just fine. It's not exactly a dynamic load. People will argue over anything.

The tensile strength of kevlar and dynema is higher than that of steel, while they have a density that is several times lower.

      Steel cables are at high risk of corrosion in off-shore environments and are rarely used. Tug operations will use simple synthetic cables (spectra, dynema). Platform anchoring cables are often a rather complex combination of synthetic cables and weights to obtain neutral buoyancy.

    This all depends on what you're hanging. If hanging art worth more than $100, use steel cable. Museums and galleries all use steel cable because it is easier and nicer to work with. dyneema is strong, but not chemically stable and will degrade over time with exposure to atmosphere and light (though obviously there isn't a lot of light behind a piece of art on the wall).

      I agree that it's easier to work with - you don't need to know any knots, just twist it and it stays. So that's a definite benefit. But when it comes to UV and chemical resistance, I don't see how one would get any degradation in a museum setting. Dyneema is used in heavy industrial applications like mooring lines and tugboats for very large ships with lifespans over ten years. Unless you're hanging up something that you're not taking down for a century, it shouldn't be a worry.

    Neat, thanks for introducing me to Dyneema rope. I just ordered some. I suspect it will come in really handy.

      It's also has a huge benefit for towing or wrenching over steel cable - there's virtually no recoil if it breaks. Steel cable will slice people in half and send wrenches through car windows and to stab the driver when it breaks.

        “slice people in half” Why I won’t drive over the cable car slot. Slice cars in half, that.

    As a climber I place my life in the hands of knots all the time, but tying a knot in steel cable is generally a bad idea since it is unlikely to bind properly. For better or for worse steel is often used instead of synthetic rope for picture hanging.

  As an amateur sailor I beg to differ. First, you can tie knots with steel wire, too. Second, I would be much more comfortable hanging artwork on a thin twine than on steel wire. Steel wire tends to be sharp and scratch and punch holes in anything it gets into contact with. Rope that will be durable and can withstand the stress of hanging 30kg artwork is still very thin. Just google it and be surprised.
