Bored up your windows so no light will come in. Throw clothes on the floor. Make sure your bed is never made. Make sure it smells like a mixture of weed and cigarettes. Post all kinds of band posters to your wall. Good luck ;)

Ok I'm picturing like 90's grunge here..... go to the thrift store and get some old flannel shirts and make them into throw pillows. Get an old grungy couch from the thrift store. Find old beat up skate board and turn it into a shelf. Oh and you can't forget about the Smiley face and Ying Yang symbols!

And of course you need a Nirvana poster!

Back when I went through my grunge stage I had covered my walls with cutouts from magazines. You could do an accent wall like that, but make sure you use sticky tact, I used duct tape and it ruined the walls (Sorry Dad). lol

I switch phases a lot like sometimes i like light and cute things but lately I've been liking more darker, soft grunge types of things. I listen to a lot of music so maybe that would help? My walls are a medium gray, and everything is based off of gray tones. What are some things I can do to achieve 'soft grunge?' thanks.
