wolf, woof

Wolf or wolf means the large wild creature that resembles a dog--
"Who's afraid of the big bad wolf?"
He's a wolf in sheep's clothing.

Wolf is also an old-fashioned slang term for a lecherous man--
He's a wolf; no nice woman would be seen with him.

Woof or woof means the thread or yarn that goes across a piece of woven fabric--
The warp goes up and down, the weft or woof goes across the weave.
The loom is strung with the warp; the shuttle is used to add the woof.

Woof or woof may also be an imitation of a dog's bark--
The dog says "woof" when we ask him his name.
Our dog makes one low "woof" when he hears the doorbell.

Now that you know that, you can say--
"She is weaving a picture of a wolf; the details will all be added with the woof."
