Little Houses on the Hillside . . . Little Houses Made of Ticky Tack

Do you remember that song from long ago??  Well, as I was putting a row of little house blocks together that song came into my head!!  Funny how our minds work!!  Anyway first row of houses.  Notice that two of the houses have perfect corners on the roof sides and two are not so perfect!!  Guess which ones are the paper-pieced houses!!  :-))
