Pufflet

a cheese pufflet; a pufflet of smoke

That scarce discernible pufflet of smoke and dust is a revolution.

Repeat with the remaining squares and line the pufflets up on the baking sheets, spacing them about 1/2 inch apart.

The sky was a turquoise blue with only pufflets of cloud; the sun lay on my neck and arms; far out, a flat sea shimmered like a blue cloth.
