A dangling what???? Does it hurt?

Roger.

Only if you dangle it in front of an old school English teacher.

I wouldn't dare.

You can have real problems with a dangling participle if the wind's coming from the wrong direction

Those type of books are a great idea that I had never thought!! Thank you for the advice!
Does anyone use color wheel? I found this one while searching for the books:

Is it useful? How it works?

P.S. Sorry for my bad english..
