Hello, me again.
How do I measure the armhole then? It has to be 24cm from where I started to shape the armhole by casting off a few stitches. Now, do I simply measure the distance from the row where I started the armhole shaping or do I measure the edge of the knitting and include the width across the stitches I cast off at the start of the armhole shaping? Does that make sense?
Maybe it's just easier to tell me how you do it I'm trying to avoid a sleeve that's puckered once I sew it in.
