1. Cover the cone first with the adhesive. A few stripes of tape should cover the cone horizontally and a few stripes also should cover the cone vertically.
2. Starting at the bottom of the cone, start wrapping the tinsel around it and continue upwards, keeping the tinsel taut and close to the previous row to prevent the cone showing through.
3. When you reach the top, cut the remaining tinsel and use a straight pin to pin the end to the top of the cone to secure it well.
