In 4th grade Arts we did some amazing things and the last project we did was with glue, salt, paint and watercolors.
First, we painted a paper with black color and then, when the paint was dry, we drew lines with glue.
Later, we threw salt on the lines. We also painted the salt with watercolors.
After that, we varnished the drawing and when we finished we put it to dry again.
Finally, the project was incredible and here you can see some pictures of the process.
