What did we do before the Internet? Actually, how did we ever get along without Youtube? It doesn't matter if you are trying to replace a washer in your faucet or make a tote bag, pop over to Youtube and you can have a real human being showing you how to do it. Even I have a Youtube channel and right now I have instructional videos for embroidery stitches.
My husband fixed the lights behind the dashboard in his truck today by following along with a Youtube video.
