It takes more time to come up with a mosaic tile design than it does to glue it down.
Problem is the materials (go through your junk drawers and jewelry boxes) change as you go along … some pieces make the cut … others will not. This is not the time to get discouraged.
If I’m on a roll and the pieces are falling into place … it takes me about an hour to glue a single light switch cover.
If I’m not on a roll … I’ve already started gluing something else.
