Timeless is a clean double column theme elegantly handcrafted for bloggers and photographers alike. It’s responsive, hi-res and equipped with fancyBox3 (lightbox).

Just like this website, I’ve been a big fan of double column themes with a sidebar on the left, so created one for Tumblr! Timeless has simple yet classy look that stands the test of time — hopefully!
By the way, I’m now building my third theme, two-column 250px grid theme with a fixed sidebar. Will let you know once completed and accepted by Tumblr. :)
