Learning to sew was decidedly one of the best investments of my time in recent memory. I was just able to mend a jacket that I really love. It's perhaps not the neatest stitching job ever, but it's pretty secure again and not in a paricularly visible spot.

The cost? A little bit of thread and about a half hour of my time, versus buying a whole new jacket that I probably wouldn't like as much. I'll take that deal any day.
