Knitting patterns for any body shape

We all know that people come in lots of shapes and sizes. Long arms, short arms, long back, etc.

So how the heck do we find just the right knitting pattern for our own individual body shape? It is easy enough to adapt a knitting pattern and make the body a bit longer or shorter, or to knit the sleeve a little longer.

It’s not so easy to adapt a pattern for a fitted sweater, or for short arms. What about pear shaped people, plus sizes, or petite people?

So, whatever your body shape ...
