I've had a 12x12 sheet of sticky back canvas in my stash for quite some time, and when a relative of mine wanted me to make a birthday card to someone who turned 50, it was necessary to try it! The card should have something to do with horses, and I don't have ANYTHING in my stash that is related to horses, so I had to pull out my sticky-back canvas and use it. I printed a picture of a horse and transferred it to the canvas. It took 3 tries before I was pleased with the picture, but it was FUN!
I've published this card in Pyssloteket's blog today - so head over there if you want more details about materials.
