I made up a Sewaholic Renfrew on my vacation as well.
It’s … ok.
I’m not thrilled with it. The v-neck turned out all right, as did the cuffs and hems. The peach rayon knit has an interesting finish with a flat side and a slightly ribbed side, so I used the flat for the shirt and the ribbed side for the cuffs, and I like what it adds. It’s a very light and comfortable shirt, except that the sleeves are a bit too snug–there were no notches to show where the sleeve pieces were meant to meet up with the shirt, so I couldn’t figure out where the ease was to go. And Sewaholic patterns run small up top if you get my drift, which I do not, and my alterations didn’t quite work to add the extra I’d need. So there are drag lines.
