When re-colouring leather that has stitching threads in contrasting colour it is important to protect the stitching from absorbing the new colour. This tape is heat resistant to enable you to dry your colour with a heatgun without melting the tape. This tape is only 5mm wide, the perfect width for covering stitching in leather, make sure the tape covers the stitching entirely so that the dye cannot leech under the tape and stain the stitching.
