I see from earlier posts that some people have Pfaff machines. I have recently started to work my way through the manual of mine from scratch because although it is ten years old I have always tended to use a limited selection of its pre-programmed stitches and have not used the machine to its full potential. I am making samples which I am keeping in an A4 binder by running off rows of all the programmed stitches using their default settings and just seeing how they perform on a single layer of interfaced calico. All is going well but the manual doesn't really show you under what circumstances you might use, for example, the 16 different overlock/overcast/mock cover hem/overlock blindhem variations and I wonder if anybody has come across any literature or online info regarding the use all of these built-in utility stitches?
