Whether you just purchased a new house, or want to give your old place an updated look, deciding on what interior decorating theme to apply could be confusing and stressful. Applying ideas that compliment your style and personality could turn your house to your dream space. To help you, here are some top decorating themes you might want to consider. For the young and bold who want fun and colour in their homes, a Psychedelic theme inspired by the 60s and 70s will be perfect. Funky furniture, swirly patterns and colours that pop like lime green and orange are main players in this style. Accessorize with lava lamps or wall aquariums reminiscent of the period. Then just install some black lighting and you're set!
