Chevron stripes seem to be everywhere these days (they are the "bunting" of 2011!) and I think they are ok. Sometimes they can hurt your eyes! Anyway, I like the look of light grey and white chevrons and made this template. I have included the blank header image, so if you want to go to town and make a fancier header - do it!
PS: Have used the "Sansita One" font in this template (from Google Fonts). I am just so in love with Google fonts right now. xx
