The history of Fractured (that’s this sweater’s name).
Swatch stockinette. Assume my pattern stitch gauge is be proportional like pattern writer’s stockinette-to-pattern gauges. Calculated size to make based on my gauge. Knit on-and-off for a year to get to arm pits. Try on sweater. It fit. Knit another 2 inches. Something is wrong. Block sweater. Realize pattern gauge is not proportional. Realize my sweater is a size too big. Experience sadness. Recalculate which size to make based on actual pattern stitch gauge. Get to arm pits. Realize armscye is too shallow. Consider ditching sweater. Figure out how to mod pattern. Keep knitting. Use up one ball of yarn. Try on. Seems ok. Getting ready to frog first attempt and use the yarn on right-sized sweater.
Lesson: Always swatch and block ALL stitch patterns used in a project. Always. All.
