Have you designed your own blog?
Let's Sermo is on a Woo Theme that is heavily tweaked. Part of the tweaking was don by me.
As for my other blogs, no, I have got them designed.
What is a blog?
I always design my own projects. Cheaper, and keeps me learning.
I tweaked both www.glosonblog.com and www.poetrytalents.com. They use the same theme but look different. (I gave Poetry Talents the same theme because I can't find a more suitable theme!)
Gloson Blog still looks a little like the original theme. I don't want Poetry Talents to look like Gloson Blog, so I tweaked Poetry Talents heavily.
Improved my CSS skills. :P
No....I used a theme.
I am planning to design one now. It will be an absolutely clean theme.
I didn't personally design mine, but the Teenius theme is custom, and the BrainBite.com theme is basically a Wootheme (Busy Bee) with some minor tweaks.
Mine is actually a WP blog. I had to convert it to blogger. SO I can say its my own my previous templates were 100% my own. But this one is originally form WP convertoed to blogger by me..
I built my themes off of a framework, so it's mostly mine I suppose.
@Sneakyheathen haha try converting a wp blog to blogger! I've designed 14 blogger templates, around 4 wp and joomla for my clients!
