Here's a quick peek at how to do collage artwork like the Pig pictured above. This acrylic mixed media piece was done by one of my adult students, Dianna Huchingson, who is very talented, much more so than she gives herself credit. She did this piece in about 2 hours and used scrapbook paper, gloss medium, acrylic paint on a canvas panel.
She started out using a pig picture similar to this one as her reference/inspiration.
First she sketched out her basic shape, and then using gloss medium, she started glueing her torn papers into place.
Then using acrylic paint mixed with gloss medium, she filled in the white space.
A few more shadows and touches and she ended up with this cute little guy!
