ERRATA
For the front, the pattern says to work the first openwork stripe of the front ‘knit two stitches (star) knit two together, yarn over and repeat from (star) 11 times’.

This will not work, as 11 x 2 =22+2 edge stitches =24 x 2=48+28 center stitches=76 stitches.

The correct version should be ‘knit two together, yarn over and repeat from (star) 12 times’.
