To make a maternity belly band, get an old knit t-shirt that used to fit your body before pregnancy. This kind of shirt will make an ideal maternity belly band, but which may get tight on your belly during the weeks of pregnancy. However, when your belly size increases, use another old knit t-shirt to make a new belly band. But the shirt you choose this time should be large in size than the previous one. The preferred material for them is one that is made with 10 percent spandex and 90 percent cotton or jersey.
Now throw away the upper portion of the t-shirt and make the top hem with the remaining cloth. After that turn the shirt’s band from back to front and lay it on a table. Fold the hem to one inch and then pin it down so you can sew the hem in a zigzag stitch by keeping it close to the raw edge. This zigzag stitch will provide stretch when you wear it, and it will prevent the stitches from breaking.
Belly Band is Ready
Now turn this band right side out, as it is ready to wear. The advantage of using a t-shirt was that you would not have to sew the bottom of the hem because it has a factory finished edge.
