I thought that the Lens-Artists Photo Challenge: Something Old, New, Borrowed and Blue was going to be quite a hard challenge.
Until I thought of one photo that covered three out of the four, Old, New and Blue. All I needed was Borrowed and in the end the photo I picked for Borrowed also covered Blue and tied in with the first.
