Darling - How to Remove the Flowers in the Header

Navigate to Appearance > Editor.

By default you will see the style.css file. 

Look for these two sections of code:

header-full-width .site-header .wrap {
background: #fff url(images/header.png) top center no-repeat;
}
.site-header .wrap {
background: #fff url(images/header2.png) top center no-repeat;
padding: 30px 0;
}

and change them to:

.header-full-width .site-header .wrap {
background: #fff;
}
.site-header .wrap {
background: #fff;
padding: 30px 0;
}
