Are these bibs for when you are feeding the baby or the toddler is feeding him/herself? Or for the child to wear when they are teething to keep their clothing dry from drooling? I found that feeding bibs only need to be as thick as a washcloth as I always put a clean one on for each feeding. The one to protect from drooling needed to have a plastic or rubberized backing as they would sometimes get completely soaked! I would use flannel backed oilcloth tablecloth material for the back of teething bibs with a really absorbent fabric on the front. My all time favorite feeding bibs were small guest towels fashioned with clothespins connected with a ribbon. So easy to launder and I used a ton of them.
