Pauline Alice's Turia Dungarees. I interfaced the sides of the bib (which are on the bias) because after 1 line of top-stitching they were looking decidedly wavy. I hoped that the interfacing would straighten the sides of the bib out a bit, which it did. Next time, I would probably interface the whole bib, just to make it a bit more sturdy.
Thank you very much to Minerva Crafts for providing the fabric, and to Ed for taking pictures!
