Collect shards of glass, old tiles or ceramic pieces from broken plates and cups to use as "tiles".
Take an empty tin.
Sand the outside down down until it is no longer shiny.
Use the Tile Glue to stick the "tiles" onto the tin. Try and keep the space between your "tiles" as small as possible, 1-3mm is perfect.
Leave it to dry.
Once dry, use tile grout to fill in the spaces between the "tiles".
Make sure to choose a colour that compliments your "tiles".
Wipe excess grout off with a damp sponge.
Once the grout is dry, polish up your mosaic tin using a soft cloth.
