Yarn: Americo Original 100% Pima Cotton Flame
Needles: 4.5 mm (US 7)
Mods: I always knit my sleeves flat, and seam them. I tapered the sleeves by decreasing two stitches on each side every 3 rows 3 times (so in total, 6 stitches decreased in each sleeve) about 1.5 inches from sleeve hem. I also did 4 rows of ribbing, since I don’t like rolled hem sleeves. I didn’t do the button or the button hole, and lengthened the cardigan substantially.
The only thing that I'm not crazy about is that the fabric stretches out at the elbows and gets 'elbow bag'. but really, that's a lot of sweaters, so... not a huge complaint. cotton yarn isn't known for it's elastic qualities, so I'm not that fussed.
