Don’t feel you have to follow perfect symmetry all of the time – a huge bookcase along an entire wall doesn’t have to mean books all upright in a row like little soldiers, or like a traditional bookshop, library or dad’s study or den.
If you’re starting from scratch, wall color paint is the quickest way you can establish your canvas, make a statement & get the home decorating ball rolling. If you’re wanting to achieve a makeover or a refresh update, changing the paint color of the rooms in your home is the most impactful & fastest way to change, & bring your room, your home to life - & also the most inexpensive. It’s like buying a fabulous new outfit, or using make up to transform your look.
All you need to do is keep thinning things out – keep at it. Home Decorating & creating the Home of your dreams is definitely a work-in-progress.
Now that may be based on one or more or a combination of the styles, that is your choice. The most important thing is that it is you & expresses who you are & your loves & creative expression!. If you would like to go with one of the styles then do so. It’s your choice. Research it. Plan it out. It’s what inspires you to move forward that’s important here.
