If the power cord I'm using is flexible enough of "S"ing or putting them in a figure 8 I will do so. If I knew I wouldn't be messing with the power cord again I would use zip ties. If I knew I was going to make changes I would tie them up with twine or use sturdier twist ties.
If the cable isn't flexible to put in a figure 8 or "S"ing I would just try to route them so they wouldn't be near interconnects. Since some of the power cables I have were also heavy I was forced to elevate them so that they would not sag from the IEC inputs of the gear I was using them with.
As for dressing them up you can buy all sorts of heat shrink and cable sleeving to make your cables look as pretty as you like.
