There is some Olivia Pig fabric by Andover fabrics. Found this by googling "fabric Olivia Pig". Try it and you'll find several sources.

My grand niece just loves Olivia the Pig and I want to make her a quilt from the Olivia fabric. I had some a few years ago but gave it to someone else who was looking for it. Now I can't find it except one with very small Olivias on it. Does anyone know where I might be able to find some? I'd like to have a panel and coordinating fabrics. This will teach me not to give away fabric thinking I can get more some time down the line.
