Great patches of weed are floating in the Atlantic.

A patch of tufty white cloud was floating serenely through the air, the only blemish in a perfect bright azure sky.

Large patches floated on the surface of the water, like scum.

Great patches of brown scum and thick foam floated across the water.

Small patches of green mist floated before his vision.

I knew nothing until I knew that we were on the floor by the great table, and that patches of tinder yet alight were floating in the smoky air, which, a moment ago, had been her faded bridal dress.

The searchlights were poking up over the park; patches of light floated like clouds along the surface of the sky.

Watercress was abundant; patches of it floated among the rocks all along the margin of the stream, and a huge mat of the spicy dark green leaves lay temptingly just ahead.

As he moved aside, a patch of blue-green floated into view, like a ghostly pool of ectoplasm.

And like a shadow becoming real, a shifting patch of darkness rose up from the dais and floated into a column that became the creature Kirk had met so long ago, in the Mandylion Rift.
