Is there someone who could cut for you? It sounds like it would be dangerous for you to try to cut using one your one eye.
A thought on the quilting, although I say this and I haven't done it! What if you put some type of a pattern on your quilt and then traced it with your machine to quilt. I'm thinking that because it seems like you can sew the pieces together. So maybe a pattern instead of free motion would be easier once you practiced it.
