Women centuries ago used and made baby slings. It's funny how history repeats itself.
Baby slings are becoming more popular than ever. If you go out and purchase a baby sling you will pay an average of $50 for an infant sling.
So if you're crafty and know how to sew or own your own sewing machine you are well on your way to making some extra money with this great idea.
You could advertise for baby showers. Sell slings for infant on eBay. There are plenty of online craft sites such as Etsy and many other sites that allow you to sell your crafts.
