I cut a piece of Pul for the bib and cut a piece of Pul for the pocket. I serged the top of the pocket, then pinned the pocket in place on the bib and serged around the whole bib. After I finished, I added snaps so the bib can be closed.
For my serging, I used a rolled hem. It’s pretty decent practice for curves so mine isn’t quite perfect, but my skill at this is definitely improving. The Pul serged way more nicely than I anticipated with the shiny side down.
