Take your grapevine bow base and, using the wire cutters, remove any unwanted pieces. This could be anything that isn't high quality or that doesn't match the color scheme you're planning.
Add your bow right to the center of the grapevine bow and fluff it out.
Next, trim your greenery into smaller sections. Use the glue gun to add them into the grapevine base.
Next, do the same with your Christmas berry stems. Add as little or as much as you like to get your desired effect.
