This Cobble Rug made by Ligne Pure will certainly add a dramatic retro look to a room. As well as the bold use of colour and shape, it's very tactile looking piece, partly because the hand-tufted areas sit above the rest of the material. Ligne Pure is a relatively new Belgium company which prides itself on its strong designs and use of natural material. This rug is made from wool and chenille pile.
There are lots of options available. £135 would get you 60 x 120cm worth of rug, then sizes go up to 200 x 300cm which costs £1100. They have several colours to choose from too. As well as the blue pictured, take your pick from red, purple, brown or beige.
