Here are some interesting ideas for creating gallery-like picture walls. The idea is great in theory but can ending up looking a bit of a mismatch if you don't stick to a few simple guidelines. I always suggest you keep it to a simple colour combination - black and white is an obvious choice but the results are always successful. It's best to stick to one colour mount card - white of course and one single colour for the frames. Then to create interest vary the size and type of the frames and the size of the finished artwork. Then fun is then all in the hanging!
