I'm working on this still, gotta do some super minor touch-ups and add the strings and seal everything up - but I'm really pleased with how it looks overall. In the photo it looks a little less yellow-gold than it is in person, and there are a few 'rough' areas that don't really show. Overall though, yay, so glad it's almost done. I've never had to put this much work into a prop before, but I couldn't imagine my SS Zelda cosplay without the harp (I'm making the white dress and will be traveling around with Impa.. so it makes the most sense for me to have it).
Anyway! If people are interested I can put together a tutorial together for this, since I took plenty of pictures. It's made with tinfoil, sculpey, and a wooden dowel. Not usually recommended for bigger props like this, but I knew I was comfortable with sculpey so I stuck with it.
Feel free to leave constructive critiques! There's not much that I can do about this one, but if I decide to make more for selling or something later, I could advice. This one has taken WELL over 20~ hours already.
