If you have watched any of my videos on dying and airbrushing, you have seen this tape. It is excellent for masking tooled leather for several reasons. It is thin enough to see your tooling beneath it, making it possible to use a scalpel and cut the masking where you need. The adhesive on this tape is not harsh to your leather and will not damage the surface when you pull it off. The adhesive also does not leave a sticky residue on your leather. This tape makes airbrushing and application dyeing much easier.
By the way, this tape is not produced any more. When I found that out I scoured the internet and bought all I could because I hate to think of such a beautiful product being wasted on door frames and window sills! Once it is gone, it will be gone forever.
