Glass ornaments need more cushioning than people expect — wrap each piece individually in tissue or bubble wrap, then nest it in packing peanuts or crumpled paper so nothing touches the box wall directly.
Mark the box "fragile" on more than one side, and choose a shipping speed with tracking for anything time-sensitive — a lost gift is far more disappointing than a slightly later one.
Order by mid-December for standard shipping to arrive in time for Christmas; specialty and handmade items often need a few extra days to prepare before they even ship.
