These are great for children, they love them.
Use them to experiment with different tiles, colours and patterns.
The advantage of this method is that you are able to work with the tiles the correct way up (flat side)

How to use these Grids
If you want to immortalise your mosaic project simply stick brown paper on to the finished design with wall paper adhesive.
When dry just lift paper and mosaic off the grid.
Place a thin layer of tile adhesive onto the surface where you want your design to be. Place you project into the adhesive paper side up. (this will be the front of your mosaic) Once dry remove paper fom the tiles by sponging with warm water. It is now ready for grouting.
