This is an example of how to make a thumbnail on scratch! Sadly there is an issue with the project, that's why you need to press left arrow key to go to step 1, top arrow key to go to step 2, down arrow key to go to step 3 and right arrow key to go to step 4. I will try to fix this issue as fast as possible. Press Space to go back to the begining. Anyways, have a great day!
