I studied bookcraft at college in Oxford. Since then it has been an enjoyable occasional hobby, and a useful source of income at times. As a grandparent and teacher I am happy to share some thoughts on bookcraft, without trying to persuade or influence ideas or sell products.I write for the benefit of readers who have shown sufficient interest in bookcraft or bookbinding to arrive at this WWW page. There will ~ eventually ~ be a contents listing. Meanwhile the links to appropriate pages will have to suffice. So as not to interrpt the flow of text links are normally provided at the end of a sentence by a reference in square brackets
Any hobby is a useful element of living a richer life. If you agree with this then you will also agree that the sooner in life it is started, the better. Bookcrafts can be started, with modest slight supervision and encouragement, from (at a guess) four or five. There are suitable ways of presenting projects that will interest such youngsters, and they will quickly produce something useful  .
Manual dexterity is not as important in bookcraft as in many other crafts. Projects can be chosen that suit the abilities of the craftsperson.
Firstly you will notice that I am using the word bookcrafts all the time. I could use bookbinding. I wish to acknowledge the skills and training bookbinders. I am not writing for them ~ or competing for their skills. A professional bookbinder ~ and there are a few around has far more skill and knowledge at his ~ or her ~ fingertips than we are writing about here. Note that females ~ and differently abled people ~ are not in any way disadvantaged.
Similarly I often mention booklets rather than books. This is because I have met people who remark 'That's not a book'. For those selling 'books' via the WWW ~ beware of other people's perception of what constitutes a book. I am not prepared to argue over this ~ just move on and have fun making stuff with paper [Arkwright].
