I love henley tees, and they are great for nursing. I made a maternity tee with a partial button placket that I can wear for the first couple of weeks of post-partum when I’m nursing constantly.
The technique I’m about to show is different than others I’ve seen around. I don’t love the tutorials I’ve found online because I don’t like the look of the finished neckbands. This is a technique I found in an old book from the 80’s that I’ve used for my kids. I like the look of this placket best, but it’s different than ready-to-wear henley tees.
