Changing the look of a living room.

Redecorating a room without spending a dime. This is a simple project anyone can do by just going into the garage or attic and grabbing a different item, changing a slip cover or area rug. Repurposing items also aids in the transformation.
*Options I considered for this project:
1) I considered buying new furniture, but I couldn't afford it (besides the furniture I have is new but I just hate the style of it).
2) I considered selling my furniture and using the money to buy new things, but realistically I would not be able to sell it for what I paid for it to give me enough money to buy what I want.
3) I even considered trying to swap furniture with someone, but if I don't like it I had no idea as to who I would get to swap for the style I like.
*Questions and unexpected events that arose during the project:
Some of the questions I asked were 1) what do I already have that I can use to make the transformation, 2) can I re-purpose something or alter some of my belongings to suit my taste, 3) if I don't have what I need can I make do with what I have?
*My motivation to do this project:
I was raised in a home where with the seasons comes decorating changes. I like to change the look of my spaces every now and then to keep things fresh. But honestly the reason I changed this living room initially is because I called myself decorating the living room to match the house and I ended up with a room I couldn't live with, so I had to figure out a way to change the look with no money. I prefer a more contemporary style, but I purchased a more rustic living room set to go with the cabin type feel of the living room. Big mistake!
*Project Steps:
I checked in the garage and found all I needed to change the look of the room. I pulled out slip covers, area rugs and various accessories to mix and match.
Advice:
Never buy furniture just to match the house, buy what you like.
Thinking outside the box is a good thing, but pushing yourself outside of your comfort zone can sometimes lead to disappointment.
Before spending money to redecorate, conduct an inventory of things you have because you can often times shop at home (among your own things) and save money.
If you haven't seen something in a long enough time that has been packed away it becomes a new thing to you.
