The document discusses experiments the author conducted to develop thumbnail designs for an upcoming project. They created several design options to choose from so they would have a clear vision. This allowed them to select the best fitting design, resulting in a more professional looking final project. The author evaluated their top designs, favoring one that was easy to read with a bright, creative look, though it felt unfinished. Another colorful design was eye-catching but difficult to read. Ultimately, the author combined elements they liked from different designs into a final piece incorporating a colorful background, glow, and legible text, allowing them to take the best parts of their experiments.
