I changed the background and header on my blog. My background is orange with bats and pumpkins for Halloween and my header is blue with bats and a moon. I think that they contrasted against each other and they are quite suitable for the theme of Halloween. I love the effect it gives on my posts because it really adds a lot of colour to this blog. I added a Falling Witches widget to my page and I think it looks quite cool, if you want the same widget, here is the website I got it from http://www.thetechwar.com/2014/07/halloween-witch-fall-widget-for-website.html#ixzz3H7rdEaTd. I hope you like my blog changes as much as I do.
