Frustrated

I have spent the last 2 hours trying to change up the look of my blog.  I have a background on here from a long time ago (it is snowflakes) and I can not for the life of me figure out how to get it off.  I wish I could revert back to the old blogger so I could make my blog look cute again instead of boring.  If you know what to do got the the snowflakes off my blog. . . .please let me know.  I am giving up for tonight.  I am so very tired of looking at this stupid thing.  I promise to have a good post tomorrow instead of a temper tantrum post!!
