I found this site today and it's really interesting with videos and links if you're interested in mixed media. Have a look at http://www.createmixedmedia.com/ and there's a free ebook with 6 mixed media projects that all feature a bit of stitching. Authors include Ruth Rae, Josie Cirincione and Kelly Snelling.
I've cleared the decks and put my big canvas out again - had to gesso all over to hide what I'd painted in October, it just wasn't working for me. This is the first time I've done a commission and I had some suggestions from my buyer which were threatening to quash my free spirit. So I'm going to go with my instinct and hope she will like it!! I can always add it to my paintings ready for the exhibition in March so no worries.
