My daughter loves writing letters and notes to her family and friends and to encourage it, I decided to combine a fun art project to create handmade postcards. I’ve been wanting to try geometric painted art for while – a pretty common art technique – so this was the perfect reason to give it a go!

Watercolor Geometric Postcard Art – Materials:

Watercolor postcards

– Paint (we used watercolors but you can use any type paint you have on hand).

– Paint brushes

– Removable tape like washi tape or painter’s tape


Step 1. Depending on the age of your children, help them section off the blank side of the postcard with tape. Let them paint and fill in the sections.

Step 2. Allow the paint to dry completely and carefully remove the tape. You’re done!

The postcards look like colorful works of art once the tape is removed. I love the different color combinations you can create and the modern look of the geometric lines.

You can tape them up on the wall for a pretty art display.

Until you’re ready to take them down to encourage letter writing and mail them off.
