New template?

I TRIED to switch to the NEW template on blogger which SAYS you can edit it any way you want to...WRONG!! It would not accept any of my changes. I wanted to switch because my banner is being hosted by Leslie, and last night my banner was GONE!! so was she! so I thought she took her blog down, but today it was back, so maybe not. ANYWAY. I tried several times to add a picture to my header and no luck, and I could not change the fonts or colors like they promised. SO Back to the old one....
