I turn Type-A when it comes to quilting and when the points don't match I go nuts. In the past I have adopted a 1/16" X2 rule - meaning if it is at least 1/16 off I'll take it out twice - at that point - if it still wants to misbehave, it can stay. The irony is that I can never find "the error" in the finished quilt that was so glaring on the individual block.
Since then, I have loosened up a bit, because I know that it will be OK/pretty in the end.
My last moment of paralysis came when I wanted to make the Bodacious Quilt with sheet-music-patterned fabric and I realized that the pattern was printed crooked. No matter what, that quilt was not going to have matching lines. It took a long time before I gave myself permission to use the fabric. The quilt turned out great and the recipient never noticed the unmatched lines. All she could do was rave about HER quilt.
Who knows, at the rate I'm going, my type-A might turn into a C-
