Whatever your requirements and choice we recommend that customers ALWAYS  send for samples BEFORE making a final decision that proceeds to purchase. We can guarantee that the colour you see on your screen will not transfer to the exact colour of the physical fabric. What you see is your individual media choice of hue, saturation, colour and brightness to view which overrides the physical colours that appear. Likewise fabric density cannot be appreciated on a screen. SAMPLES ARE FREE AND AVAILABLE IN ORDER TO MAKE THE RIGHT CHOICE.
