For this funny idea you’ll need:
* different coloured paper
* a pair of scissors
* pencil
* double-faced adhesive tape
* cord
Cut some birds out of the paper and put some tiny stripes of double-faced adhesive tape on the back side.
Remove the upper part of the tape and stick them on your window. Add some “lines” by using the cord.
This idea was inspired by this fellow 😀 .
