I visited IKEA this weekend... again. : ) I noticed that it is a great resource for mid-century style looks for your home. If you want the look, but not the "vintage" look on everything, IKEA is probably a good pick. Personally, I think that when decorating with a certain era in mind, you should try to stick to the authentic vintage pieces. But, we all want something shiny and new every now and then!
Happy Decorating!
