I want to design my own blog skin~

Just like my title says..
I want to design my own blog skin...
but..
My idleness just forbids me to do that...

After watching弯弯's blog..
it gave me an inspiration to design my own blog...
yet i finally know how to manage the tool in adobe photoshop...
but..
i just felt tired and lazy..
because this blog skin is nice too!!

I don't know whether I should change it or not..
