Is there a standard direction for the zip slider on a bag with a side handle? I think I have put it the wrong way around on this one! How long is too long a thread for saddle stitching? I have been practicing a few things on this bag. Rolled edges, piping (I made it by hand skiving a peak down the middle of a longish strip of leather and folding), attaching zips, just using what I have to hand. The handle is too low but it gets a bit too bulky to where I had intended to put it. To get around piping part of this bag in one go it would have taken 4 meters+ of thread. I tend to not go above 2 meters at a time as it seems so much slower to go bigger that an arms span. Is this just me being a newbie? Does it make sense to do it in 1 go?
