There’s something so special about a handwritten letter—especially when it shows up exactly when you need it most. That’s the magic of “Open When” letters: a sweet, sentimental gift that gives grads a little love (and a lot of comfort) during their biggest year of change yet.
Whether you’re a parent, sibling, BFF, or favorite auntie, this DIY gift is heartfelt, affordable, and honestly? One they’ll probably cherish more than any dorm accessory. Here’s how to create the perfect set of “Open When” letters for the high school grad in your life—plus 10 thoughtful prompts to get you started.
💌 What Are “Open When” Letters?
They’re exactly what they sound like: letters to be opened during specific moments. Each envelope is labeled with a scenario—like “Open when you’re homesick” or “Open when you need a laugh”—and inside is a note that’s personal, encouraging, or just really freaking sweet.
They’re perfect for grads heading off to college, trade school, the military, or just moving into their next season of life. Whether your letter is funny, sentimental, or spiritual, it’s a way to stay close even when you're far apart.
✍️ How to Write “Open When” Letters for a Graduate
Step 1: Choose Your Prompts
Pick 5–10 scenarios they’re likely to encounter post-grad (scroll for ideas!). You don’t need to do too many—just the ones that feel right.
Step 2: Get Cute Supplies
Grab envelopes, cute labels or stickers, and nice stationery or index cards. You can go all-out with scrapbook vibes or keep it simple and sweet.
Step 3: Write from the Heart
This isn’t about being a perfect writer—it’s about being real. Share stories, inside jokes, advice, memories, prayers—whatever feels personal to your relationship.
Step 4: Seal & Bundle
Seal each envelope and label clearly. Bonus points if you tie the set with a ribbon, add a card explaining the gift, or tuck them in a keepsake box.
