A reader (hi LM!) asked if I would share how I created my header.
I made it using PicMonkey with the help of this tutorial on the blog guide book.
To make my collage I used the 'Facebook cover photo' collage. Then I slapped a banner over it - and title- and then I re-sized it to fit my blog width. All done in PicMonkey.
*The biggest mistake I see bloggers making with their header is not properly resizing it to fit their blog width.
Here are a couple of experimental ones I made before I officially titled the blog Somehow We Manage.
Hope this helps.
