Here is a video which I discovered which presents a lot of sophisticated DIY decor projects which would fit well in a contemporary home:
Many of these projects have a minimalist appeal to them, which is why they would work so well as part of a contemporary style. At the same time, that gives them the versatility to fit well into other décor styles as well. So if you do have a more rustic home, some of these projects would still look awesome (especially the one with the pressed plants). They are all quite creative, and none of them look particularly challenging. I am especially amazed with what you can do with black paint and a pillowcase.
Personally, I cannot wait to give these a try! I hope that whatever your style, you find at least a few of these projects perfect for your own home! Video by Drew Scott.
