I've done this before, but for some reason I've drawn a total blank this time. I'm binding a table runner with pointed ends. The points are "normal" angles (90°), but the other four corners aren't; they're approximately 62° each. How in the world do I figure out how much of an "overlap" to leave at those corners when I fold them and continue attaching the binding by machine so as to be able to then fold the corners over neatly for the hand sewing part? (I hope that was a bit clearer than mud!)
I've just ripped the binding off for the second time and I'm getting a bit flustered. Thanks!
