Last week my son and I experimented with watercolors and crayons to make some crayon resist Valentine's Cards! They may look a bit amateur- ish, but they were fun to make! Plus, nothing beats a home made Valentine's card :)
Here's a simple tutorial I put together for you:
white card stock or watercolor paper
Step 1: Draw a design or write a Valentine's message on the front of a folded piece of white card stock or watercolor paper. This is kinda hard to do because you can't see very well what you are drawing or writing.
Step 2: Load up some watercolor paints on a paintbrush and paint over the area you just drew on with with crayon to see your design come to life!
