The soil separator paper works well for muslins and is nice to work with, at least for a basic first fitting muslin. The fabric sticks to itself so it is easy to position seams together, and also easy to see where the garment is too tight, or there is not enough ease, as the fabric certainly has none.
The pattern, Vogue 7833, went together well and hangs nicely. I think I will like this coat very much. The coat tapers in at the bottom, which is nice, but I had altered the shape a little when I lengthened the coat. It is not quite right, I eliminated a little width right where I needed it at the hips and I will have to add that back in, plus probably another inch or so.
The only other fitting problem for me is that it is a little snug across the shoulders: It feels snug when I stand still, and the tightness is quite noticeable when I move my arms. Although I do need a little width across the shoulders, I am wondering if part of the problem is the raglan shaping. I think I will fix the shoulder width first and see how that feels. I will have to be careful as I don’t need extra width through the bust, just through the shoulders, and I have to think a little bit about how to go about this on a raglan coat.
