Little sewing sloppiness

Don't you hate it when you make a mistake on something that you have done often enough you shouldn't make a mistake? Like making your famous cookies, and leaving out an ingredient. Or in my case, stitching in the boning on a nursing cover completely BACKWARDS yesterday! Since the boning is crucial to the cover, it has to curve a certain direction...and I stitched it in the opposite way. Oh well, I just took out all the stitches and redid it. It must have been a complete brain cramp. No worries, though, Linds, you are worth every stitch:-)
