I made some cute little miniature plates the other day. Well, didn't actually make the porcelain plates, there were ordered from a website and delivered plain white. But, I printed out some nice plate designs on decal paper and transferred them onto the plates. And I gave them an outline with a golden marker pen. If you search for "vintage plates" you get a whole bunch of images that you need to scale to the correct size. I used the tutorial from this site: http://carolynslittlekitchen.blogspot.no/2010/09/tutorial-decorating-plates-with.html
Easy peasy and great fun!!
