One final wall covering that makes a splash of a different sort comes from Magscapes, the inventors of magnetic wallpaper. There are two different coverings, the MS Plus for use with strong magnets or the MS Lite for lower power sheet magnets with high and low ferrous content respectively.
The rolls can have liner, dry wipe and paintable finishes and the MS Lite has a printable option, which is where the fun starts. As the Magscapes stand you can have a lot of fun printing your own wallpaper, but with a cost of around £30 per square metre you might want to limit yourself to a colourful band across a wall.
