I’ve been working on mastering the Negroni shirt pattern and the flat fell seams were one aspect that I just wasn’t happy with on the first version I made. I also put the cuff buttonholes in the wrong place, so overall it wasn’t exactly my best work.
So of course for the next version I chose the softest, floppiest linen possible: Antwerp Linen in Chambray. It’s gorgeous, but made of 100% linen so there’s not much body to it and an incredibly soft hand. These are great qualities in clothing, but not so much for the construction part. If you choose to go this route, I suggest you invest in some good starch, Best Press, Flatter or something similar.
Because of my choice in fabric, I had to do a little extra with my seams, but first let me show you how to do a basic flat fell seam. These are perfect for the side seams of dress shirts and jeans, but are a good alternative with fabrics that like to fray.
First you will stitch a regular 5/8″ seam. I use my walking foot throughout because it works great and I don’t want to change feet unless I have to. If you prefer, you can use a regular foot for this part. Stitch, then press to set your seam.
