Birthday cards for your sister
Sisters are your first best friend and your first rival, often on the same day. A HeartCraft birthday card lets you say the soft stuff without having to say it to her face: balloons, candles, a cake, a few photos from your childhood and your letter at the end.
You’ll make it in our birthday editor, birthday.myheartcraft.com.
Cute & Sweet is soft and full of hearts, Bestie is loud and playful for sisters who are basically best friends, and Sky Lanterns is dreamy and sentimental — lovely if she lives far away now.
Whether she is your didi, your little sister or your sister-in-law, send it on WhatsApp in the morning or drop it in the family group for everyone to see.

What to write to your sister
Happy birthday to my forever partner in crime. Thanks for keeping all my secrets (and only using a few against me).
Didi, you were my first role model and you still are. Happy birthday!
To the little sister who stole my clothes and my heart — happy birthday.
Frequently asked questions
Can I add old childhood photos?
Yes. Photograph old prints with your phone and add them — they appear as moments before your letter, which is usually where the happy tears start.
Which design is best for a sister?
Cute & Sweet for a soft, affectionate card, Bestie if you are basically best friends, and Sky Lanterns for something sentimental, especially when you live apart.
Can I send it to my sister abroad?
Yes. It is a link, so it opens anywhere in the world, and international payments are supported with local pricing.
