|Young children need help telling the back from the front in many garments, and when you are sewing, that ups the difficulty for them in IDing back and front. One day I had a small scrap of foldover elastic (FOE) and realized it would make a really good tag inside the back of pants for my DD. Since then, I have taken to adding a piece of FOE when I close an elastic waistband. It is non-irritating on my children's skin and does the trick of keeping the back clearly identified. I even put it in my own garments on occasion!
