At The Crafts Dept. I came across a very nice DIY idea from. They show there how you can customize a lamp from scratch. All you need is a cheap lamp, colored tissue paper, scissors and adhesive tape. As an example you can take the IKEA Regolit lamp. This takes only three Euros! Cut nice round shapes from the paper and paste it around the lamp. For spring and summer you can take a cheerful color like yellow or orange, while in autumn and winter, for example brown or dark can go. Fun!
