Cathedral Windows is a beautiful design, originally inspired by a postcard a friend sent to Paula of the (now demolished) Chicago Stock Exchange Ceiling designed in 1894 by Louis Sullivan in the Art Nouveau style.The colors are a little bit Mardi Gras and include purple,green gold and red on black. The Calendar quick and easy, because the kaleidoscope is precut, and then a little strip cutting. This includes the illustrated instructions to make this Wall Hanging as well as a preprinted 8 1/2 by 6 3/4 inch muslin insert with the calendar printed on it. The finished size of the Wall Hanging is approximately 10 by 20 1/2 inches. Pre cut Kaleidoscope Block and 3 fat quarters included.
