I have made tons and tons of bibs for grandkidlets and my darling kids friends..kids.. whew... lol I always use a double layer of flannel or terry cloth..used the same for burp cloths also. The cutest darned thing I found when my first grandbaby was born was the entire body bib, I made several of these. Our little guy would get all spruced up for church and then urp up all over his cute outfits. Sooo nana to the rescue! These worked like a charm to keep his clothes clean until he arrived at church,sometimes he even wore these all thru church on a bad reflux day. Here are a couple of photos of them.
The pattern can be found here, I have no affiliation whatsoever.
