I just realized that I hadn't shown you all a picture of the green Super Simple Summer Sweater since I reknit it. Here it is!!
Pattern - Super Simple Summer Sweater
Yarn - 4 strands of dk cotton
Needle - 15mm straight needles, 15mm circular needle for the neck
This sweater knits up easily in a weekend. It is just simple stocking stitch with a garter st band at the bottom and a bit of waist shaping.
The next version of this sweater is on the needles. It is an all over lace pattern. Not nearly as fast of a knit as it is knit with a single strand of yarn on 4.5mm needles but still very easy.
