Even when quilting, there are times when I need to ease in a little, especially when attaching borders. Not able to keep that precise 1/4" after all these years. Even if those long pieces start at exactly the same size, the feed dogs have a tendency to feed the lower fabric at a slightly quicker pace. Not enough to matter, except over five feet it does make a difference. I'm with Dunster's--slow down approaching the pin and see if it will hit it or not. Take it out if you must.
