Scattering pick or clip decorations to your tree adds a new dimension and is a quick way to make an obvious theme to your tree. You can stay with your same base theme (eg silver) then add a big red poinsettia clip to create a quick silver and red theme for the year. Next year you can switch out the red poinsettia clips for purple hibiscus clips.
Clip floral decorations are great value and fill up the tree quickly. They also fold down well for storage and are durable over the years.
