In episode 4 of Craft Roulette, hosted by Mary Gunn FUNN, the challenge was to create a craft project based on four random parameters. The first parameter was to incorporate a pocket into the project. The second parameter was to use the colors yellow plus two additional colors. The third parameter was to include an envelope as an element in the project. And finally, the fourth parameter was to use blending brushes.

With these parameters in mind, the participants had to think on their feet and come up with creative ways to incorporate all the elements into their crafts. It was an exciting and fast-paced episode, showcasing the improvisational skills of the crafters as they worked with the random parameters to create unique and beautiful projects.
