Sister 70th Birthday Cards

Show your sister some love by sending her an awesome personalised birthday card with Cardly. We have hundreds of artist-designed birthday cards for sisters that are as weird, wild and wonderful as she is. Let her know how special she is by personalising your sister’s birthday card with a happy birthday message and doodles that look like they’re drawn in ink. We’ll print your card on quality stock and post it to your sister in a lovely envelope with a real stamp.

Whether she’s your twin sister, bossy big sister or sweet-as-pie little sister, there’s nothing quite like the relationship between a sibling and their sister! With Cardly, you can send your sister a happy birthday card that’s been designed by our community of amazing artists and made personal with a message that’s crafted by you.

Start by choosing the perfect birthday card from our range that’s designed to suit all types of personalities. Whether she’s a girly-girl who’s into fashion, a tomboy who prefers sports or a sister who refuses to fit inside a box, you’re sure to find the perfect birthday card design for your sister with Cardly. You can even upload your own photo to create your own unique sister birthday card.

After choosing the card, it’s time to write your sister’s personalised birthday message. Our amazing editing tool takes what you type and turns it into handwriting that looks like it’s written in ink. You can play around with the writing style that suits you, from cursive, neat, messy and print.

Once you’re happy with your sister’s birthday message, you can add doodles for an extra splash of personality. You can add drawings that say something about your sister, such as her favourite hobbies or foods, or go for traditional birthday doodles like balloons, cakes and champagne.

Send Birthday Cards for Sisters

Cardly makes sending happy birthday sister cards easy. You don’t even have to leave home to go to the store or the post office. Once you’re ready to send your card, we’ll print it on quality, environmentally friendly stock and pop it in a craft envelope with a real stamp. We’ll even print your sister’s address in the same handwriting as you’ve chosen for your birthday message.

We print and send birthday cards to sisters to over 55 countries. Once we’ve received your order, we work out which of our UK, USA, Australian or Canadian locations is closest to your sister so we can print and send it from there. This ensures that your sister’s birthday card arrives as quickly as possible while also reducing the impact to the environment. If you order before 10am Monday to Friday, we’ll get your sister’s birthday card in the mail that day, with next day delivery available in the UK, as well as Express Post and Priority Mail available in Australia and the USA.

So whether it’s your little sister’s birthday card, big sister’s birthday card or a birthday shout out to your sister from another mister, let her know you’re celebrating with her by sending a special sister birthday card, with Cardly.
