When I first bought my serger I was kinda terrified of it (the speed, the knifes!). But now, after six years, I know that I will always be serger owner. The things that scared me at first are now the things that I really value. However since I learned to master the basics I felt like I hit a plateau so when I saw the book Serger secrets on Amazon I decided to give it a go.
And I am very glad I did. This is the sort of super thorough, initiated sewing book that I prefer. Serger secrets pretty much covers everything you want to know about a serger, great photo tutorials with info on everything from settings to thread choice plus a great problem solver chapter. But the deal breaker to me is that it shows so many new things that I had no idea you could do with a serger, like making bound button holes, piping, zipper insertions, lace heirloom and much more. Though some ideas in the book is pushing a bit too far aesthetically - just because you can serge a patchwork vest (!) together with piping and bells (!) doesn't mean you should. However I am a firm believer that pretty much everything can be made to work in some ways, so I'm sure that these ideas could be useful for some.
