PET felt is made from recycled material. This means there can be colour differences between batches. Everything ordered in a single order comes from the same batch. With repeat orders, however, it may be a different batch. In addition, PET felt sheets have a front and a back and a fibre direction that you need to take into account during installation. How visible this is varies per colour. When processing the sheets, our advice is to place them in the same direction to keep any colour differences to a minimum. Unfortunately, we cannot take back orders once placed or sheets and products once ordered. All orders we deliver are made to measure.
