Decoration ideas for minecraft?

Hey I'm looking for furnishing ideas for my minecraft house who has tips?

A petrus cross

Build an aquarium!

I have an idea, I'll try to explain it to you now

So you make a notch in the wall about 2 blocks to the back 4 at least then come on the back 2 flowers and in front of it comes glass

I hope you know what I mean

And if you want to expand your house try it with a pool in the house and if you dive then there's a door through which you come into a secret room (although I do not know if that works on minecraft done on a fake app, but you know that yourself best)
