Cheer a whimsical and textured holiday theme.
Curiosity is a simple, clean, and elegant theme.
Embed is a simple and elegant one coloumn Twenty Twelve child theme.
Mimbolove is a simple and customizable theme with support for a custom menu, header image, two column layout, and a footer sidebar.
Curiosity looks very nice and professional. I’m a big fan of those Jquery sliders, although I frequently replace them with a Hype document. Many of my clients enjoy hype because it does what flash used to for a lot of their pages.
