Thanksgiving Message to Employees?

I would like to send a nice and professional Thanksgiving message to all my employees, thanking them for their hard work at my company.
I will send this message by email. I want it to be a message they appreciate and consider it real.
I don't want my employees to think I'm sending them the message because I have to.
Any ideas? What is a good Thanksgiving message for employees?

This is a message I found in a website, it was received by an employee and he was very happy about it.

"On this Thanksgiving, I wanted you all to know how much I appreciate the hard work you do for me. I am truly blessed to be part of an organization with such fine, professional people as yourselves."

I hope it helps. Sometimes you just have to sit in front of the computer and write whatever comes to your mind. They might appreciate it more if it's real and it was written by you.
Just a suggestion, good luck.
