If you only buy one book on serging - that's overlocking to us Brits-, get this one! It's packed with ideas and tips. After ages struggling with chains, this book gives me a simple way to tie off a chain! It has more info about tensions and what the over and under loopers do than the handbook that came with my 'Brother' overlocker! (Shame on you Brother!) It's written in an easy to understand informal style... it is a bargain, order yours today! If you want to get more out of your machine. Happy serging!
