I am coming to the finish line on Gedifra Pattern #1487 and getting ready to block it. I am very confused on the blocking chart. The back and front are knit the same and the chart is in cetimeters.

My confusion is:
The left side says 40 for the length. The right side says 38 (36/34) - my size would be 36 - Are they referring to the back??? Same thing with the arm hole - left side says 15 and the right side says 17(19/21) - my size is 19.

Can someone shed some light on this? I am confused.

Thanks.

That may be cms, not inches. 20cm would be about 8" which sounds about right for an armhole.
