The Olunda is a shadowbox frame displaying 9 pretty boring pictures of ferns. The back of the frame is stapled on, and the staples are relatively easy to pull out with pliers. This allows you to replace the fern pictures with your own.
Each fern picture is sized 110 x 175 mm.
I printed pictures of the NQDC tarot on bristol card paper, cut them out and glued them on the fern pictures with a dry glue stick. I then stapled the back on again.
