Deleting a post made in error

Could anyone reading this tell me how to delete a post made in error to my blog? Is there someplace that I could go to learn the basics of blogging?

As you can see, I haven't done much with my blog. I'm at the end of a major remodeling of my 1980s ranch house. We are currently working on converting a bedroom to a study. We changed the location of the door so that we now enter the room from the foyer rather than the hallway. I will post pictures when it's finished. My daughter (Amy's Crafty Creations) and I went thrift shopping yesterday and we found some great bargains. I'll post some pictures soon.
