Picture Centerpieces for Reunion

I needed to create 17 centerpieces for a reunion.  The specification was that they had to display old pictures for people to stroll down memory lane during the reunion.  I had a minimal budget. I took old wood from behind my shed and cut it into 8 inch pieces.  Then I nailed them together in the shape of a box without a bottom.  I took old nails and nailed one nail into each side of the boxes.  I then dry brushed the boxes with white and aqua acrylic paint.  I placed a canning jar in each box and miniature roses and carrot flowers and some broccoli flowers in the jars.  I punched a hole in each picture and hung them around the boxes.  These could be used at type of gather and almost anything could be hung on the nails.
