Re: Sail tape not sticking
If it is not sticking to the cloth then either the tape is really low quality, or the sail has something on it preventing adhesion. Ask your local sailmaker for a piece of "insignia cloth". It should stick to any part of the sail. If you are sticking it to a stitched area you may need to rub a hard object on the tape to press it onto the cloth between the stitching.
