So do it yourself, especially in wall art, doesn't mean that it has to look cheesy. In fact, it's one of the elements in a home where you can get away with just about anything and it looks like a million bucks, literally. I like the use of for instance, shadow boxes, they are frames that have a deeper interior. So that you can do things like putting on a really beautiful broach and framing those. I love antique broaches that you would find in a garage sale or something like a piece of jewelry, or a collector's item. Some people collect coins, some people buttons, different things like even bottle caps, you can turn into art work. I love using shadow boxes for just that reason.
Fabric is another thing that's really graphic and looks amazing on anybody's walls. So if you have maybe a yard of left over fabric that you used to recover a chair or; let's say you had bedding or you know, a pillow that just has seen its better days and now is worn out; instead of throwing it out, cut a piece out and then even if it's frayed, it has that kind of like that shabby chic or vintage look. Frame it in a really inexpensive frame and then you're done.
Also, another thing that you can use as wall art are tapestries. You can hang your fabric or even a rug as your wall art. Maybe the rug, you don't want to use anymore as a rug, you want to give it new life. Hang it as your wall art. There's so many different ways to add accents your walls. So you really don't have to spend a ton of money. Always think up something that's really personal to you and it'll make your space feel unique. It will also be inexpensive and it's a really cool weekend project.
