Need a NEW LOOK!! Please help!

Haven't been on too much blogging lately however need some advice from you experienced bloggers. I want a fresh look, I am now a full time stay at home mom and will be intending on blogging on new experiences, crafts, and such and want a fun looking site in which to do it on. I love the easy layout of this particular site and do not want to change off of blogger, however would love to update my look. Please post any info on cute and free layouts and designs to help me get started... I have been using a cute one however I hate how the background is white and pretty plain. PLEASE HELP!!
