Not sure what you mean, but there are generally two preferred methods of bundling a loose cable with minimal risk of damage to it. The standard spiraling coil and the over-under coil. Both have different uses and they both keep it tidy while never going under its bend radius limit.

For tidying an already in use cable, depending on its type/usage and without trimming it, you would either use the over-under coil or fold it over itself. If you need to fold it over itself, you would try to make each fold as long as reasonable, while keeping the ends of each fold loose enough to be above its minimum bend radius. (eg. Cleaning up cabling in a shared raceway with ethernet and AC power)

Sharp bends tho.
