Marine Upholstery Vinyl - this collection of vinyl's are one off's, not to be restocked in the future. Available in sheets or varying roll sizes, please check each type for descriptions. These tend to be thicker than faux leather/synthetic vinyl so be careful when layering with other vinyl's. Some tailors chalk marks could be found on the upside of the vinyl. It is always recommended to do a small test before commencing your major project.
