I have created a housing for a tea light that is in the shape of a star and it has interchangeable face plates to suit all occasions. The face plates have different patterns. there is a Snowflake, Hearts, Swirl, Lines, Houndstooth, and Squares.
The face plates are pressure fit onto the housing and are very easy to change out.
The front and back of the housing can have plates so feel free to have 2 of the same or change it up and have a snowflake on one side and hearts on the other. Or any other combination you want.
If there is a pattern that you would like. Leave a comment and I can see if I can make that happen for you.
