I would think textures, shapes and possibly raised letters and/or designs. Do they read braille? There are tutorials online. Good luck and stay safe.

You can purchase Braille birthday cards on Etsy if you decide you don't want to attempt making one.

Make a pop up birthday card. If the kid knows braille then write something thoughtful on your card with braille by making dots in the paper with a pin! I don't really know alot abt this but I hope it helps

Hello Maz,

Make it smell nice by adding perfume or add inside a sachet of lavender, Rosemary, or other sweet smelling things, Design the card in relief. Stick shapes on to front that the child would recognise. Best wishes.

Oh I love the idea of lavender ... Never would have thought of that 🤗 I did attempt raised braille dots before but wasn't confident on what I had written 😋 thank you all for your truly inspirational ideas.... Guess I'd better get crafting 👍

Paper flowers onto card stock. Also, the foam stickers that are in shapes. Use puffy paint to spell the child's name or look up braille of their name, if the child is old enough to have learned.
