This is a great introduction to Photoshop brushes that does not need Photoshop. Every single step is provided in the tutorial so no previous design skills are necessary. This project includes everything including the brushes and can be accessed with Photopea. Photopea is a free online photo editing program very similar to Photoshop. Photoshop is not needed. The lesson is provided with a link to the Google Slides Presentation and as a Powerpoint. The Google Slides presentation is fully editable (step by step). This works great with Chromebooks. My students had no problems using their Chromebooks.
