I made two buttons for you all, I know that is something you were asking for and I figured I could help with it. I made two so that you can choose which you like better. Hope you like.
Make sure you check out stephanie's amazing buttons for Dewey as well, then you'll have a selection to choose from. Hopefully everyone who wanted to honour Dewey with a button on their blog will find one that they really can embrace.
Feel free to use them on your sidebars!! I can send you the full sized image if you click on the email me button above and send me your address. If you are having any trouble at all using these let me know!
