DIY/Design Tips………?

OK so i have a small, boring, messy room.

and i need some tips on how to open it up,clean it up(and keep it that way),and some decor even with things i can diy at home (preferably using things that you can find at home just lying around) thanks!

There's not really much you can do there… You will end up spending money do refresh your space no matter what. But you can do it fairly inexpensively. I don't know where you are but where I am we have a Habitat for Humanity ReStore. You can get cheap paint and all kinds of fun redecorating and remodeling materials. Do some research and find out if you have anything like this near you. Search the web for DIY bedroom makeover project ideas.
