Learn the Reverse-Paper Mosaic Method with Cathleen Newsham

Description: If you have questions like these, this workshop is for you:

  • How are the mosaic murals in the New York City subways fabricated and installed?
  • How do I make a mosaic totally flat with no sharp edges using materials that are different heights?
  • How do I create a large mosaic mural when I only have a small studio space to work?
  • How do I install a large mosaic without tiles falling off during the process
  • What adhesives should I use for a mosaic mural that will be installed outdoors?

Learn the newest Reverse-Paper Mosaic Method so you too can create flat mosaics using smalti and glass.  Creating a mosaic for a public mural or for certain architectural uses like flooring, showers or back-splashes can be challenging even for a seasoned mosaic artist.  Cathleen will show you in this 3 day workshop how to create a flat mosaic using the method that she has developed after 27 years of experience, She will enable you to have the confidence to create a durable mosaic that is fabricated in such a way that the installation process will be a breeze.  

Cathleen’s method enables you to create large mosaics in smaller sections, so even if you have a small studio, you can create large projects.  She will show you how to work from a photograph, drawing or painting in the reverse method, enabling you to do everything from your studio, (including grouting), so all you have to do to install is apply the correct thin-set to your substrate then adhere your completed mosaic “puzzle” pieces.  

The method Cathleen uses is similar to the way the majority of the NYC subway mosaics are now created and installed, and the method she has used to create mosaic floors, murals and other projects that must be flat and have no sharp edges, which is what most architectural and public mosaics require.  

We will each be creating our own small 8”x8” works using Cathleen’s method, then adhering to a wedi-board backing.  You can use your own art source, or Cathleen will provide you with a variety of options.  You will be able to take this piece home and hang it on your wall using the hardware that we will affix to the wedi-board.  

Wedi-board, smalti, glass and adhesives will be included in the total cost of the workshop.  You will also receive a detailed hand-out with information about the tools and supplies we will be using to create the mosaics
