Untangle your wires with pool noodles
Uncovered foam is acceptable in one’s room if (and only if) it will be hidden behind something else; for example, if the TV is hiding it. You can use woggles to keep wires untangled neatly throughout your house.
On the one hand, many loose wires make an awful sight. They can make a room look messy and cluttered even if it is not. On the other hand, if the foam is in plain sight, it doesn’t look good either.
