I got something similar to the books you mentioned but about woodwork
 
	so gonna buy some for my collection too ( I collect those types of books )
 
	the website you mentioned looks pretty good as it tells you what type of leather you need
 
	so for someone like me that never did leather apart from a leather apron but by hand not with machine 
 
	thanks
 
	I forgot to mention I am trying to learn how to sew with a machine ( singer 45k)
 
	thanks for the plentiful info guys I really appreciate it
