I also made these a while back and just stumbled upon the picture..
I used a pack of bibs from wal-mart, so their not the nicest quality..but I was experimenting. Now I can do these embellishments on home made bibs, and it will be wonderful!
I love the yellow with this fabric. It feels very 70's to me.
I used wonder under so I could easily trace the patterns out and cut them. Then I ironed them on, and top stitched over the whole thing. I loved how they turned out.
