I have always been in love with big metal, wooden or acrylic letters that are displayed on a wall in a house. It looks so striking and bold and quite different.
What is great about it is the ability to use the whole wall space, and in fact use the floor space too. Buy letters in any size, any material and any colour and they will always look good together. Secondhand letters are also great-check your local market for some cheap finds. You can change it up when you get bored….mmmm, I love it!
