How to build a design board to hold the mosaic tesserae until they are mounted on their support? We’ll show you.
First, you draw and color your design.
Then, you cut out parts of the design that ‘hang together’ in some way.
From the top of the first panel, here are the shirt hem and the shorts.
Here we are using a section of clear plastic painter’s drop cloth taped over a design.
Next, you cut a piece of fiberglass mesh the right size to fit over your design. Handle the mesh with gloves over your hands, if you don’t want to itch for the next three days.
Batten down the edges of the mesh with tape.
When it’s time to glue tesserae onto the mesh, mix some polymer-laced thinset cement for the adhesive. Put it into a baggie and cut off a corner for a squeeze spout.
