My wife cut waves for me out of vinyl foil, and I was then allowed to apply them. It looks cool and can also be removed without residue if necessary.
For the first time, already pretty good and almost without bubbles (Blasen in German). ๐๐คช /BadDadJokes
And this is a PNG created from the project file before the cutting. The colours match almost perfect, as she did not use a colour pipette of a photograph.
