All bibs and burp clothes fabrics are pre-washed before they are made to help reduce any shrinkage or colour run after they are made. They are backed with towel for better absorption and to make it softer on the babies skin. They are then over sewn on outer fabric around the edge and multiple times over the whole bib/burp cloth for extra strength and to help with any shrinkage. The bibs close at the back of the neck with valcrose, making it easy to put on and off the baby/toddler. There are also 3 different styles that you can get the bibs made in. Can be made for boys, girls or gender neutral
