How do you proceed?

If you have very smooth stone coasters, I recommend first applying a primer layer.

This can be done with gesso or a layer of white acrylic paint.

With wood it is not really necessary, but if you prefer that, it is always possible.

Then you sketch your drawing on the coasters with a pencil, so you can print out pictures and cover them with carbon paper.

Once you have done this, the fun work begins, painting your drawings with different colors.

You can go wild with regular acrylic paint or with posca pens.

Once the paint has dried thoroughly, varnish it with a good varnish.

You can then wipe the coasters with a slightly damp cloth, but never put them in the dishwasher.

I wish you all lots of fun again.

Greetings Agnes.
