Wordpress: to customise or no?

[Sixtiesmax]

Hello

I'm new to Mnet and blogging. But need a helping hand with wordpress. I've figured out 'infinite scroll' which sounds to me like it should be a spa treatment but can anyone recommend a good FREE design in wordpress? And if you have customised, was it worth it and how much did you shell out? I am struggling with design and colour limitations, as you can see

Many thanks.

Not free, but I searched themeforest for hours and paid a small amount for a theme. I have now used the theme on several websites, and they all look quite different.

SaltandCaramel is my personal blog

Jump! Mag is a preteen eZine

It was definitely worth paying the money for it. The only thing I regret is not going for a template that included a mobile theme.

Thanks for help. . Good point about Mobile. I have WP app but it's not great on iPhone so that's something to think about for future. It's pretty time consuming finding way around WP so tips much appreciated.

PS: Money talks!
