I do pin the points, although I've never thought of glue basting them; mostly they stay matched. The big problem is that the whole patch shifts when I get to that bump, so when I'm finished, there's a clear detour in the seam - not much, but enough to mess up the finished patch. I've tried using the needle down button, stopping, and then verrrry slowly sewing over the bump, but even then it wants to shift. It may be that I'll have to suck it up and hand-stitch the points. I'm slow at handwork, but slow is better than losing my temper. I had thought of pressing seams open, which is sort of what I prefer, but I was following the pressing directions in the pattern. (I'm still new enough to quilting that I don't feel confident straying from the directions.)
