I like the idea of incorporating a line-art leafless birch branch into the logo, possibly as the dividing line between "Sovereign Birch" stacked above "Herbal". Possibly a single birch leaf off the 'h' in Birch. Basically please include birch somehow, recognizably. (I work as an herbalist, it's important that the birch be identifiable.)
I'm not sure if I want the words the same or different sizes (ie, Sovereign Birch bigger than Herbal, vice versa, everything the same size...)
I am slightly more partial to a black and white logo for ease of printing, but am open to colors. Please do the logo in Pantone colors if possible, for ease of future printing.
I've included a word doc with additional branding information (fonts, colors).
I look forward to seeing what you come up with!
