Olde Riverside Tree Offshoots

I'm trying to combine a new technique with an old look - photos of tree silhouettes (from my old neighbourhood, Olde Riverside), stitched through, but on a paper collage background.  The old way involved 'framing' each piece with a border of black fabric binding, wrapped around canvas.  With this new technique, there's no border, and I even debated whether to delineate the tree photos, as of old (and, decided I needed to).
