1. Heat up the glue gun. Simply start at the bottom of the cone and a a drop of glue and press the end of the garland into the glue. You can press the point of scissors to hold the end down until glue sets which prevents burning your fingers.
2. Then continue by adding glue along the bottom of the cone and pressing the garland into the glue. When you reach the beginning end, continue by adding the next row above it. At this point you do not not have to place glue constantly down. Just add a drop of glue every inch or so and press the garland into the glue. Continue in this manner until you reach the top of the tree. At the top, be careful using too much glue. Because the top point of the tree is small, too much glue will actually melt the tip off.
