why I don't do cutwork

I'm stitching on Plum Street Samplers freebie called Coffin Buzz which has a lot of lettering and I made a mistake when I started one of the lines. It was 6 stitches off and had to be frogged. So, I started ripping out my stitches. Here's the part that will make you groan--I accidentally cut stitches on several letters of the line beneath the line that needed frogging before I realized what I was doing! So instead of re-doing one line, I wound up doing one and a third lines.
