For Ellie, on her 18th birthday
How it works
From your heart to their someday
Write
Pour it out in your own words, on stationery you choose: wildflowers, starry night, or a well-loved recipe card.
Add a keepsake
Tuck in a photo, or record a voice note so they can hear you say it, years from now.
Choose their someday
A birthday next spring, graduation day, or the morning they turn eighteen.
Seal it with wax
Pick your seal. On their day, the envelope opens with a little bit of magic.
A letter for every someday
The moments you want to be part of, even from far away
For a grandchild, grown up
A letter they open on their 16th or 18th birthday, full of who they were when they were little.
A love letter
For your sweetheart, to open on your anniversary, Valentine's Day, or a quiet morning when they least expect it.
Graduation day
Words of pride, written long before the cap and gown.
Their wedding morning
A little blessing waiting for them on the biggest day.
A new baby
Welcome a little one, and leave a note for the day they can read it themselves.
Dear future me
Hopes, wishes and a few reminders for the person you're becoming.
Just because
A surprise to brighten an ordinary Tuesday, months from now.
