So, I know that the Tiger Tank needs some short-row bust shaping.
Maggie Righetti's Sweater Design in Plain English has a great section about how to plan for and create short-row bust shaping. I always pull out my copy and read through this section before I sit down to do the math.
It's not difficult at all, if you follow Maggie's formula. She spells out what to do step-by-step.
