The only prop replica I have done was a Jawa Ion Blaster from star wars for my daughter's halloween costume last year.
I would LOVE to see the Jawa blaster! Please post or give me a link if you already have.
Here is one more prop, a bottle of butterbeer. I can't claim to have done the graphics myself, but I printed them out on sticker paper and "assembled" it.
I just thought it was neat.
