Enriched Stitch just posted a group of photos of the Parisian landscape by Abigail Cecile that is called "City of Lights." The canvas is available from the shop or your favorite store can order from Fleur de Paris who is Abigail's distributor.
It appears to be an amazing piece of stitching. The stitch guide is available at the shop and the companion piece, "London," will be available as a guide shortly.
UPDATE: Becki has finished the Rooftops of London.
UPDATE #2: Stitch by Stitch in Larchmont has a stitch guide for the Rooftops of Manhattan, written by Mary Ellen Winnicki.
