Are they for the Stations of the Cross prior to Easter? I grew up in the Catholic faith and immediately made me think of that because the ladies of the Rosary Sodalitry had to replace the stations with new covers during the week before Easter. They usually made like small canopies over the plaques. Like valances over curtains. it was just easier than trying to cover like an ironing board cover. Sorry that's the best description I can come up with.
