What did Chinatsu make? In the first season on Episode 6, they play with oil clay, and the clay model that Chinatsu make was censored.



What exactly did she make? Are there any pictures without the censorship?
It's likely a nod to how terrible of an artist she actually is.  That is, when she tries to be good.

Earlier in the same episode, she was reading off a picture book to the group.  At the very least, it freaked Yui and Kyouko out a ton.



The likely inference here is that her art sculpture is so bad, that censoring it is the only sane way to show it to the rest of the world.
