I know Pastelmat paper can be curved, but I was surprised and disappointed to find the 1/2 sheet size pastelmat board was also curved (or warped) when I received it. I thought the whole point of mounting it on board was to avoid this warping and keep it flat. What is the best way to keep it flat please?
Thank you for your enquiry. I am sorry to hear that your paper has arrived warped. Could you please call the sales office on 0800 980 1123 and a member of the team will be happy to advise.
