Can I add to this please..as a total newby i discovered that while trying to saddlestitch soft leather (goat) it unknowingly went out of shape...ie it stretched as I was pulling the edges together as I was sewing....I discovered this only when I had finished!....If I had used glue prior to my stitching I think I would have made a better job..fortunately I'm making a rustic style tobacco pouch and the style will sort of let me get a way with it but of course..I know it's there...so next time if the application is possible I'm going to glue first and then stitch.
