This is one of the other panels, viewing from the front side. You can clearly see the factory hem stitches.
This is the panel I just hemmed, viewing from the front side. The stitches are not so easily seen. My mom taught me well. :)
This is how I do it. I put in a piece of white thread so you could see it against the dark background. I just barely catch a few threads on the panel and then again on the hem, using a single thread. It goes fairly quickly, and I think the finished results are worth the effort.
Mending is becoming a lost art, I think. But I look at it as a form of recycling. I've found a lot of items at the thrift shop that just need a little TLC with a needle and thread and they're as good as new. Not only that, but it makes them original :)
If you're not comfortable with stitching and mending, I found this cute and fun book with tons of ideas. It's eye candy for someone like me who loves to stitch!
