Particularly board books take a lot of abuse in our house, and attempts to mend them with ordinary sellotape are never that successful. Ordinary stuff goes yellow and unsticky after a while, and scotch tape tears too easily.
Is there something specially designed for the job? I dimly remember seeing tape in library books with some kind of thread built into it -- can normal mortals get hold of such a thing?
We have so many books out of circulation atm because the joins have gone, and it's such a waste.
