google Mickey Mouse embroidery there will be a bunch that comes up. I don't know your feelings on copyright but brother is the only company that has rights to this copyright! which means most of them are aggainst copyright laws!
If you are wanting to do something with the ears I would A) be careful Disney is strict about their copyright..and why not just use a plate and saucer to draw the "ears" and then cut the circles out of black fabric and raw edge stitch them on to your tote? This saves on cost and you can make it as big as you like!
