3. If you're going to fasten the bib with snaps, you should definitely reinforce the neck with fusible interfacing--otherwise, the snaps often won't set properly, and can pull out of the material if a lot of force is used. If you're going to fasten with Velcro, you don't really need to add interfacing, but I like the structure it adds to the neck area. Alternately, you could cover the entire bib with interfacing, or even a layer of batting or plastic. Your two bib pieces should be sitting front-to-front, and if you're using interfacing, iron it to the outside of one of your pieces, so that it will be inside when you turn it after you sew: 4. Sewing T-shirt material can be a little tricky. You want to use a small ball point or stretch needle, and you'll usually have to loosen your thread tension and lengthen your stitches, as well. If your material gathers, your tension is too tight. A medium zig-zag stitch will always work, but the stitch edges will show through, then, at the roundy parts of the bib after you turn it. I don't think that looks bad, but it's something to think about. If you're worried that a long, loose stitch won't be strong enough, though, know that we'll also be top-stitching around the whole bib again later:5. Don't forget to leave a hole, and then turn your sewn bib right-side out. You can iron it at this point, or just smooth and shape it by hand, but then top-stitch again around the entire bib. This flattens it, strengthens those earlier loose stitches, and I think looks very nice as a border. The top-stitching also neatly closes the hole you left for turning the bib. 6. Here's where you choose your fastener. I dislike hand-sewing Velcro, but frankly, snaps are usually overkill--I mean, it's a bib, people, not your pants. I like a sturdy fastener as much as the next person, but having a fastener much stronger than your material will wear on the material a lot when you open and close the fastener. That being said, I still mostly use snaps--the snap fastener is a tool, and I'm a sucker for tools:
And that's it!
