Melissa Prince Designs just posted a photo of Suzie's finished Titanic coaster on Facebook. There's a guide available via Suzie's shop, The Enriched Stitch, and you can order the canvas from Melissa.
UPDATE: Here's the Cinderella coaster. Apparently Suzie is stitching the entire series.
UPDATE #2: Breakfast at Tiffany's
UPDATE #3: Star Wars, Superman, and Forrest Gump
UPDATE #4: Here is the model for the Wizard of Oz coaster. Stitch guide by Suzie Vallerie, like all the others.
UPDATE #5: Jaws!
