Create a bead mix of autumn colors with all the colors listed for this project. Pour enough of the autumn bead mix into the container to cover the bottom, then pat some in place going up the sides. For the Napkin Holder, you only need to go up two opposite sides, not all four sides. Carefully place the container in the preheated oven and allow the beads to melt. Check the results every few minutes and pull the container out when you are happy with the effect. The beads will flatten and stretch when melted, creating an interesting texture. Remove the container from the oven and allow it to cool. If you used non-stick spray, carefully wash the cooled pieces thoroughly by hand with dish soap.
