Deck the halls (and the gifts you give) with boughs of holly. And mistletoe. And an amaryllis or two. Greenery boasting red blooms is the perfect way to inspire the holiday spirit, which is why it is the perfect centerpiece for this enclosure card. No watering necessary.
Thank You Notes should be sent out as soon as possible after you receive the gift. One to two weeks is the sweet spot, as your note should be a thoughtful gesture, not a reminder for what was given.
