I made the Papercut Circle Top on the weekend. It is a very easy pattern. It is basically a big circle with sleeves. The sleeves have a cuff which could be halved (I have mine folded up which I quite like) and the whole thing is bound. The binding took longer to make and sew than the rest of the cardigan (and looking at the photos now, the binding needs a good iron).
I used some merino wool blend jersey which has a beautiful drape. I bought it off ebay and the colour was called Dutch Blue. Everyone in my house says it is purple, but I am just not a purple person so I am pretending it is blue.
I don't love it hanging open, it might be different, when I am not pregnant, but I love it closed with a brooch. It is really comfortable and I will keep at eye out for more wool jersey that I can make another one out of.
