Assuming you would like tips on the best places to put a fairy door, here are a few ideas:
1. In your child's bedroom - This is a great option because it allows your child to have easy access to the door and also makes them feel like the fairies are visiting them specifically. Just make sure that the door is placed high enough so that your child can't reach it and accidentally damage it.
2. In your garden - If you have an outdoor space where you can put the door, this is also a great option. It gives the fairies a place to come and go as they please, and also means that you'll get to see them more often too! Just be careful that the door doesn't get wet or damaged by the elements.
3. On a tree - This is a really magical option, as it looks like the fairy door has been there all along! It's important to make sure that the door is securely attached though, as you don't want it falling off and getting lost in the leaves.
4. In your home - If you don't have an external space for the door, or if you just want the fairies to be able to visit you inside too, then placing the door inside your home is also an option. Just pick a spot where it won't be in danger of being knocked over or damaged, and make sure that anyone who comes into your home knows not to touch it!
