I often leave small pieces I have created on my walks etc for others to find.
A few weeks ago I started to paint some left over cardboard I had and also some small canvasses and I don't think I have shared them with you yet.
For the canvass boards I used stencils and various 3D mediums from gels and pastes (again, using up old stash). I added colour with sprays and paints, watering down some and flicking them across the canvasses and then adding some words with a posca pen (I love these pens as they seem to take on most surfaces). I finished them with a light spray of a sealant just in case it rained when I abandoned them.
The cardboard was even easier I just drew direct onto the white acrylic again with a posca pen. I drew a couple of my favourite Studio Ghibli charachers of Totorro and a soot sprite!
Once again I applied a light coat of sealant.
Some of these have already been abandoned, some I have yet to set free!
