>>2579419>4 pieces of a3 paper>aluminium foil>packing/gaffer tape>baking papercut each sheet of paper to end up with a tapered end to hold my speedlite, and with a 30cm^2 opening at the other end
lined inside of it with aluminium foil, and taped a sheet of baking paper to the main opening
I lined a box lid with foil to use as a reflector also
might be worth adding that I don't really know what I'm doing
