The first "weapon" I set out to make is not really a weapon, it's more of a shield if we want to get down to specifics. There aren't many reference images of this item on the web, I basically had to pay extra attention during the game and come up with my own interpretation.
I started with a cheap store-bought umbrella. I think it was $8. You can see how ridiculously long the handle of her umbrella is. My umbrella has a very short handle. First things first--I carefully removed the nylon from the umbrella. You can see that this umbrella is tacked in 3 places, goddamn this was a cheap umbrella.
Now you have the skeleton of the umbrella. And the entire nylon piece is basically a circle, made up of 8 triangles. I measured the width of each piece, which in my case happened to be 13". From the center to the edge, the length of each triangle was 18.5". Easy pattern.
This lace had a bit of stretch to it, so it's pointless to pin (look at all the open weaves) and the chalk is going to leave too little of an impression. I use weights to keep the stretch lace from shifting, both on the pattern and on the area around the pattern. You can get legitimate fabric weights at the crafts store but I was kind of lazy and just used whatever heavy, small objects I had lying around.
