All that he saw was fog, a heavy gray blanket.

A heavy blanket of fog sat close upon things now.

The route is under heavy blanket of snow all year round.

As if someone had covered me with a heavy blanket.

The young woman just sat across the fire from him, wrapped herself in a heavy blanket, and lay down to sleep.

He went back to the bed and took the heaviest blankets.

The blast of light and warm air hit him like a heavy blanket.

Covered completely by a heavy blanket she was almost invisible.

A blanket so heavy that she could not draw a breath.

He could feel something lifting off him, like a heavy blanket.
