I emailed the designer last week, because I was confused about the stitch count and the odd number of stitches. This is her reply. I reread it again today and think she is saying to do what Sue suggests (1,3,2,4).
Edit: read it again and am still confused. Back to experimenting.
"Candice, ypo are correct, thanks for pointing the mistake out to me.Yes you are increasing every other stitch
If you have cast on 68(72) sts you should have 103(109) sts after the decrease round and yeah you need odd number of stitches as this is a stitch pattern in a round, and this is a modified linen stitch pattern. Why is that? as the stitch pattern will be joined with a new round that switches and sometimes after a marker you would have to slip 1 to start the new repeat. LIke you would knit 2 last sts before the sts marker:
k1, slip1wyf, slip marker (and next round u have to start by slipping 1 and then knitting one, so you) slip 1, knit 1.
Just try it it works. Sorry for the confusion and i appreciate your feedback!
