Using the same colours but different patterns is an effective way of mixing and matching with furnishings. Check out these great cushions from Superette, both black and white but with a different pattern.
ShutTheFrontDoor have made this easy! Mix or match these cute little tealight holders.
I love using canisters like these for storing bits and bobs around the house. They are also great for tea, coffee and sugar storage on the kitchen bench. There are soooo many to choose from including different colours, patterns and sizes. You could choose to have the same colour and pattern but have different sizes. Or have all the same size but different colours and patterns. There are endless options!
These great little candles are from Collected. They have just two different patterns but you could mix up with colours.
