I used a photobooth photo of Katie to make a portrait out of little 3/4" x 3/4" pieces of poplar. After working with poplar for a while I have also been impressed by the range of colours and tones in the wood, from purples to dark browns, loads of greens and lots of lovely creamy raw seinnas. I ripped down strips of the wood and milled it to long 1/4" thick by 3/4" strips and then chopped them up to make the squares. I then divided them roughly into tonal families and then drew the image on a piece of 1/2" plywood. Once I was happy with it I drew a 3/4" x 3/4" grid over it and laid out all of the squares until they looked right, then glued them down with wood glue.
I then made a frame out of solid poplar and finished it with a few coats of shellac, rubbed with steel wool so it's protected but super smooth to the touch and a nice dull non-shiny finish.
