Blog Renovation?

last night someone told me that i needed a new blog template. i would do this. i tried to find one. i like having the three columns, and not everysite can accomodate that. i found a site that has three column templates. there was one that was really cute. i copied the code and erased my html, after saving somewhere else, and pasted the new code. it wanted to delete a bunch of my widgets. if i were starting from scratch then i guess i could do this, but i don't want to have to redo all my widgets. you all will just have to suffer with a colorful, but plain, blog from me.
