Agent Query Cover Letters

So, I have a question for anyone who has considered submitting to a literary agency or has submitted.  Have you ever written a cover letter instead of a query letter?

I’m working on one for the Sheldon Fogelman Agency, and I’m just not quite sure about it. I was wondering if anyone has some advice about typing one of these up.  I’ve got the synopsis down pretty good, I hope (gutting some of my query letter) but it’s mostly the bio I’m struggling with. I mean, I have not published a thing, anywhere! How does this sound to everyone?

I wrote Lulu Buys a Hat after my own experiences hunting for a good hat that wasn’t too expensive and looked just right. It took several shops, and a best friend in tow, to find the best hat in an area where hats are not a common thing.  When I am not writing picture books, I write weekly on my own WordPress blog, entitled Kate’s Bookshelf.  I was referred to your agency via the Writing and Illustrating blog, run by Kathy Temean.

Jazzy enough?   Yep, I am relying on you readers for some help. You’ve been great in the past and I am SOOOOOOOO nervous I’m going to do the wrong thing. I’ve only queried two agencies in the past.  So, any help you want to share would be great.

Alright bloggers. Have a marvelous Wednesday evening! I’m off to pick some jostaberries. Yes, that is a real thing. Ah, farm life. I wish it was more of a writing life (by which I mean published author writing life)
