How to Repair a Map or Foldout in a Book
When you want to repair a map or foldout you have to remember a few things about how folded paper works. I used to overdo it with the strength of the tissue I used for the repair and I used to think I had to strengthen every fold preventatively. I know better now and can show you the safest way to repair a map so that it holds together for a very long time. If you have books with maps or foldouts in them you will be familiar with the kinds of tears that happen along the folds. It can be really hard to repair them because of course they are attached to the book! You have to be so careful not to create more tears.
