Mods:

• tubular cast on/off with 3.25mm
• straight ribbing (not twisted) on 3.5mm
• body knit flat: WS 4mm RS 4.5mm
• smoother transition from rib to increase + stockinette using this TECHknitting technique. Transition done on RS, 3.5mm needles. WS, purl, 4mm needles. RS with invisible decreases, 4.5mm needles
• Vent in ribbing
• Decreased stitches at neckline only one stitch in

This was a quick & easy knit and just the right project to work on even tension in ribbing, St st, and tubular cast on/off. Improvement needed.
Did a bit of math to get the size I wanted even thought the gauge was different. Happy with the way it turned out!
