Problem is I have never been able to find a grid that was made just for hot shoe flashes that were affordable. Well, I happened to stumble across these guys, Honeycomb Grids , and they have the perfect products to use for your hot shoe flash... you can but them ready made or DIY, in addition to grids for flashes they have grids for beauty dishes and strobes, as well as gobos, snoots and wraps. So if your in the market for a quick, cheap grid solution check these guys out.
