Writing is easy....pic attached.

Some days, I just want to go buy a bowling ball.
I'm open to ALL tools.
I have "The Complete Rhyming Dictionary," (published 1931, rev 1991), and "Barlett's Familiar Quotations," (published 1832, revised 2002...1832..wow). Both are 5 lbs and classics, but I haven't touched them in a couple years, until right now. I use Rhymezone when I'm pressed. And I'm going to check out the site that Bob* (I think) mentioned that drills down a bit more. The names was something-dinosaur-ish (I think).
Of course, it's more satisfying when the muse just drops the whole song on you.
