I very rarely do it. I would rather rip the seam half a dozen times than fool with trying to get it glued just right and then dried and then sewn, only to find out, I didn't have it matched up perfectly. As you can guess, I have a love/hate relationship with glue. I have been know to sew a horizontal tacking seam to hold a point in a specific place to get it sewn perfectly. If you leave the ends about an inch long, they are very easy to pull out.
