I decided to adapt the OWW resource a little bit and instead of writing prayers on post-it notes we wrote them on strips of plastic cut from 'bags for life' and wove them using looms made of cardboard boxes and gift ribbon.  One stays with each of the two churches - until such time as we're bored of them and (recycling) bin them!

Each woven prayer unique and beautiful, intertwining our petitions and prayers for the world of which we are a tiny part
