It’s a superb way to make a room interesting, lively and homely. The more mixing, the better! Above is a wonderful example of that fact. Gorgeousness on a wall.
I also like the pic left, found via Abigail Ahern’s facebook page. In her signature eclectic style mixing (and mis-matching) is essential. And adorable! It’s quite a job to find the odd pieces, but the only way forward is to start collecting.
I am a firm believer that the common denominator in the mix – the unifying link – can and may be one single thing: art that in one way or the other speaks to you. And always remember, no rules apply.
