Christmas tree picks are especially good for filling in the gaps of your Christmas tree. To use them, place larger tree picks in the bigger gaps in the tree, and smaller ones in between the ornaments. Adding picks to the body of the tree will also make it appear larger, so you can fill out and fluff up your Christmas tree. Using various styles of Christmas spray and picks like tinsel, berries, pinecones, and flower clips will give your tree a varied and unique look. You can even use Christmas tree picks in other areas of the home, such as in vases on tables.
