I tried to explain it several times but now I decided to make a video. (see it here)
I usually start sketching the outlines on a piece of cardstock/chipboard/canvas. I recommend using a thicker background that won’t curl.
Then I apply something that will stay dimensional after drying. I usually work with "Potch 3D Effect" or "3D Lack" varnishes (see the note on supplies below). But you can experiment with paints and mediums and find a paint/medium/glue/structure paste/whatever that works best for you. I don’t usually use my paints/mediums on surfaces they are primarily intended for...
When the 3D pattern is dry, I paint over it with acrylic paints. [I sometimes gesso the surface first.] Crackle paints look nice when I have a more intricate pattern with lots of small spaces.
I start with a coat of background colours - just a simple background layer, nothing fancy.
Note on supplies:
When I'm happy with the result, I highlight the raised outlines with a white contour paint.
Note on supplies:
- Most of the paints and art supplies we get here are from Germany. I'm sure there are similar products on your market.
- 3D varnish: The two I use (Potch 3D Effect by C.KREUL, 3D Lack by Nerchau) are intended for “découpage” (napkin technique). Both are opaque when wet, transparent when dry. So they can be used to create a “glaze” effect (similar to Glossy Accents) on a finished piece.
- Outlines: The ones I use (Glas-konturen Paste (Outlining Glass Paste) by C.KREUL, Relief Paste by Marabu, Cerne Relief Paint by Pebeo) are intended for glass art - to create an outline on glass or porcelain which you then colour in with paints. But because they are water based, I use them in my art. I tried Enamel Accents but the consistency is too thin for a detailed outline. Stickles might work too... The key is in the thin applicator and thick consistency of the paint.

I call them doodle-tiles, I'm not sure what they are
good for but I had fun making them ;-)
