Scroll down .... this web site has lots of ideas for you. There are many panel quilts here that have been enlarged. They are all free patterns too. You can click on any of them for a free pdf download.

I would love to see pics of what you come up with!
I just wanted to add that the pdf files give dimensions for the borders added to the panels. If there are any panels close to the size of your supernova, this might help.
