Replace elastic in pajamas the quick way, by attaching the new elastic to the old and pulling through. But before you do that make sure that you have measured the new elastic.
This could also be used to replace elastic in skirts or trousers. It would be even quicker if the elastic was not fitted snugly into the band.
Different types of elastic will have different levels of stretch. A non roll elastic will not have as much stretch, but it will not roll like braided elastic which tends to curl. The garment type will also affect the type of elastic you use. I have included a link here to a company online who explain about elastics's. It is called "What type of elastic do you need".
