Make your own books and albums! Designed with creativity and flexibility in mind, these glue strips allow you to create your own album covers in any size. These 30cm glue strips can be cut for shorter books, doubled for wider spines, or cut in half for thinner spines. To use: Cut glue strip(s) 0.3cm shorter than album cover on each end, (that's a total of 0.6cm shorter than the book spine). Remove adhesive backing and place glue strip in centre of spine. Don't use glue strip without a album cover.
