LET'S START WITH THE BASICS.
Here's what you'll need: a piece of paper or a notebook a measuring tape and something to write with .
The first thing you need to do is draw up the layout of your room you wish to change. Take a second to look around and see what you've got. Here is an example of a plan for an apartment and a legend with what everything means. You don't need to draw up everything of course, but you can make notes of whatever it is that you think it will be useful to you later down the road. And trust me, it will come in handy. But we will start with something smaller and easier.
