Cups-Hand paint bingo designs onto plastic goblets to set at each placemat.
Of course, I usually use this when working with thread to dress up a plain placemat or filet crochet piece.
Placemats are a fun addition to any table; get out craft materials and have each person create their own placemat or one for someone else at the kitchen table.
If you like, you can use a large plate or charger on top of the placemat that you will leave in place throughout the meal, serving other courses on smaller plates you place on top.
If not, simply leave the center of the placemat empty.
