I have long wanted to make a domino set for my daughter, not with numbers but with pictures to develop logical thinking. Pictures are selected by match (moon-stars, toy-baby, etc.). You just need to erase old pictures and draw new ones! Use sandpaper, nail polish remover, etc.
Also prepare the cover from the box:
Wipe off the dust, degrease the surface with alcohol or vodka. Use sets of pictures I used or even photos of your family members. Domino tiles are better to be painted with acrylic. My daughter helped me ;)
When all the pictures are painted and dried, varnish the surface.
Meanwhile, think on the back surface of the domino tiles. I decided to just stick a pretty wrapping paper. Then varnish it.
I used this paper to perfect the lid.
Wait when all dries and play! That's all! ;)
One can also make a pebble domino set:
Good luck! :)
