I made a table runner that comes to a point. The 90deg. corners are fine, but the 45 deg corners are all wonky. What did I do wrong. When attatching the binding on the front side, I sewed off through the corner at the 1/4" mark and stopped. Folded up the binding at a 90 deg. or 12 o'clock, I then folded it back down and let it come down enough to follow the 45 degrees so it would follow along the next edge I'm attaching it to. I did try to keep the fold even with the top of the 45 (at 12 O'clock. Should I have let it come down on the fold on top more into a 45 at the fold? Help... I'm prepared to rip the binding out, but only if there's a fix for what I have. Apparently you have to click download to see the PDF showing the problem
