I bet you have loads of small items and remnants that might be sitting inside drawers and boxes, although they could actually become very handy if you wish to decorate your walls in a more personalised way! Just take hanging hooks, nice ribbons and strings and go for it! You can really place a variety of things on your walls that could be matched with each other in terms of colour, of texture or atmosphere and make a great decoration that every time you look at it, it can give you a big smile:-)
