Hi! I did the Central Park Hoodie Viking version and used different cables you can see the not so great pics here:
It is a nicely versatile pattern and I know some people put a zip in it.
I also have these bookmarked for future projects:
Olive Branch Yoga Hoodie
A better pic of the yoga hoodie
That Weasley Girl
(goes from child to adult size)
A Drops design cardigan
Also, there are a few people who have turned Rogue into a cardigan and I think there are instructions for doing so on the girl from auntie website.
