Pin the second piece of the Velcro onto the other end of the elastic. Check the fit of your pregnancy support band by trying it on, making sure that the Velcro front and back pieces are aligned properly. If the Velcro is not aligned, move it until the support band gives a proper fit, and pin the Velcro into position.
Pregnancy support bands are useful to alleviate backache during pregnancy, since they properly support the weight of your belly. Pregnancy support bands are available to purchase in most baby and maternity stores, but if you have your own sewing machine, it is easy to make your own support band.
