Spiral bound books are great options for address directories for schools and organizations, recipe books, workbooks, booklets, etc. They conveniently lie flat when opened. For most spiral bound projects, we use a mix of machines and hand work to get it together. The holes that the spiral will thread through are punched into the paper and then the spiral coil – which comes in a multitude of colors – is started by hand and finished with a machine. It’s fun to watch the coils thread!
