1. Buy or make your own pattern.
The easiest way is to just take a bib you already like and trace around it. Give it a bit of extra space for sewing, cutting mistakes, etc. Otherwise you can purchase a pattern from homemakers, bloggers that sell them. A simple google search will render you lots of options.
2. Select two material types or pieces
You may want to use flannel on fleece or PUL on fleece, terry cloth, flannel, microfiber, etc. My current cut is of 12 inches by 12 inches. A typical flannel is 40-43 inches long. Fleece on the other hand is about 44 inches long. PUL is great for easy wiping.
3. Trace your pattern twice.
Trace once on each type of material or both of the same. This will give you the flexibility to reverse easily or create a more absorbent bib.
4. Cut both pieces.
5. Sew slowly.
Sew both sides together facing each other. Sew from the middle bottom counterclockwise. Leave three fingers space between your start and end at about ½ inch from the edges to flip out. See pictures for you visual learners.
6. Cut off any excess sides.
a. This will reduce any bunching up when you turn it around and sew your trim.
7. Flip inside out and sew again.
a. Flip the bib inside out from the bottom opening, carefully. You pull too hard and you will tear the threads. Sew a nice trim to flatten the ends. Here you can switch out your thread for a nice color to make the bib pop.
8. Add Velcro or add snaps.
For Velcro cut the pieces to match your ends and sew in. For snaps you will need a hand press and snaps. See picture for view of the plastic snaps. I have used kamsnaps and have loved them in my own cloth diapers and now bibs. I love the availability of colors. It adds a special something to your homemade projects.
