Apron out of jeans. looks to be one piece using the whole leg split at the center front or center back. leg style or shape would play a part in the final shape of the apron. wide leg or flare jeans would make a fuller apron I imagine
EDIT: Pattern is now available at my store! I couldn't resist making a polka-dot Emmeline apron for this month's Tie One On. For those of you wondering about the release date for the Emmeline Apron and the Mischievous Gnome Messenger.
