Here's a few fan-related cross-stitch pieces that I've done:
The White Tree of Gondor from the third "Lord of The Rings" movie.
Logo from the "Serenity", the "Firefly" movie.
Hogwarts Shield from "Harry Potter", before I took out the waste fabric.
The "Liberator", from the old BBC science fiction series "Blakes 7".
The T.A.R.D.I.S.!
Sorry for not having credits on all these patterns- I don't have the sheets at my fingertips. I am tremendously grateful to the creators, though, as I really enjoy stitching pieces of fandoms that I love :).
