It's me. I did hear from Jacque Larsen of The Lilypad digital site. That site has each designer handle the particulars of what all you can do with their designs. She said it is ok to use her designs for blog headers. For non commercial blogs with credit given of course.
This link will take you right to her designs.
So if you were looking for one, that is a choice. I emailed a few other designers, I'll update as I know.
Oh! ShabbyShoppe has what they call "blogware" which are adorable predesigned blog header thingies. You stick on your own title and even insert photos! *how cute to put a photo of your best cards?* There are also "buttons" that it gives you, which makes my brain bleed. I think they can be used on your side bar? anyhow They are only $2.50, so that's an option.
Here is a link to them. Also it's apparently ok to use the purchased kits from them to design your own header thingie. I'm really unsure about the free kits they offer under ShabbyPrincess, but maybe those too?
So that's what I've learned.
