Fun painting activity : watercolor and mixed media postcards

When you want to learn new techniques, it can be a good idea to try them on postcard sized watercolor paper.

You will have fun with these painting exercises, the postcards are easy to make and they will look great.

Here are a few techniques you can try to make watercolor and mixed media postcards.

Salt textures

salt textures on watercolor wash

Paint a wash on the paper and sprinkle salt when the wash is still wet but just before the point where it will start loosing its shine.

Once the wash had time to dry, brush off the salt, you should see the flower like texture made by the salt.

drawing with markers on top of watercolor

Draw with black markers, add designs on top of the background.

simple pattern with marker on top of watercolor

Start with a simple pattern and slowly add more to it.

make your own watercolor postcards

Leave a bit of the background without marks.

layering watercolor for background

Paint a darker wash in the same tones on the background and on some places of the design if you want to.

Using a natural sponge dipped in a watercolor wash, paint textures in the background.

Wax resist

oil resist with pastels

Drawing with oil pastels is a simple way to add resist ( areas that won’t be painted) on a card.

Here I am using a white oil pastel on white paper so it is easier to see when the paper is hold flat against the light of a window.

Once you are done with the design you can start painting a watercolor wash on top.

The paint won’t go on the paper in the places where you did use the pastel, although tiny drops can still dry on the wax.

The finish postcard, I like the tile-like appearance.

Plastic wrap visual textures

mixing watercolors wet into wet

Wrap paper will make the paint form geometric textures, this technique works on regular watercolor paper as well as on yupo paper. Here on regular paper, I am painting an irregular wash mixing tones of blue and yellow.

While the wash is still wet, place some plastic wrap on top. It will stick to the paper in some places and make folds in other places.

Once the wash has dried, take off the plastic wrap and start adding designs with a marker.

Here again, once you are done drawing you can add more contrast by painting the background a bit darker.

wet into wet watercolor on yupo paper

You can proceed the same way on yupo paper. Start by painting a wash with a few colors mixing wet into wet.

Plastic wrap will also adhere to yupo in some places, forming geometric textures.

Remove the plastic wrap once the wash has dried, which will take longer on yupo paper because the paper is waterproof.

Then start adding designs with a marker, you can use tissue paper under your hand not to disrupt the watercolor background.

Here I did draw Flower overlapping each other.

    Beautiful ideas. Question, how do you keep your paper from curling?

    • Thanks Christine 🙂 you can either use thick watercolour paper or tape your paper to a board.

    Thanks for the inspirational informative ideas! You are doing exactly what I like to do! I have been using alcohol inks on Yupo, but not other media and I really like what you are creating with other media!

  • Thank you so much for these tutorials! I just stumbled across your site today and am so inspired. I’ve always wanted to create art like this but never figured out how to do it on my own. So thank you, I can’t wait to get to work creating things for friends and family! <3

    Great ideas! One question – why do you use yupo paper vs watercolour paper?
    Thanks for sharing these fun projects!

    • Thanks ginimom21770600 🙂
      All these techniques will work on regular watercolor paper and on yupo paper. The advantage of yupo paper is that any texture technique will work very very well. You can see it with the plastic wrap texture on this post, it was done on regular paper and on yupo paper, it shows more on the yupo paper than on the regular paper. I also like to work with markers on yupo paper as the surface is very smooth.

    Love this step by step on the cards….Thanks for sharing this Sandrine.

  • Great idea!

  • Great idea for a craft workshop.

  • You always seem to know what to add AND when to stop! I greatly admire that delicate process.

  • Thanks Kathy :), for the postcards I had an idea for each design of what I wanted it to look but not a precise composition and all, the patterns kind of grew organically.

  • Your designs are flawless. Do you plan ahead or just create the wonderful balance?
