Blogger’s template designer is a feature which you should definitely use. The template designer can be found in the Design option. Even I have got this template from the template designer.
Firstly, choose the template you want for your blog. Then you need to design it. You can also choose different ready-made designs of the template. You can even choose different backgrounds for your blog.
You can even change your blog’s layout. There are 8 options for changing your blog’s layout.
