For this easy DIY project you can choose any colors for your ribbon depending on the color scheme you have in mind.
If you want to add more texture to the tree, alternate between different styles of ribbon, such as glittered, patterned, and satin ribbon.
Before you start attaching the ribbon to the foam cone, you need to prep your ribbon by cutting it into equal lengths about 4" long. If you are using a larger cone, you will need slightly longer strips of ribbon.
Next add a dot of hot glue to one end of the ribbon strip. Take the ribbon in your hands and fold it inward to glue the ends together.
I found that creating a type of "assembly line" with the ribbon strips made this process go much faster.
