Don’t do this.^^^. For a couple more dollars buy the sunrise. It is made for 3x5 cards. Has a clear window and you can lift it for another window underneath. It is a good solid piece of kit. I’ve had mine several years and it has held up well. When I ordered it I told the owner I was trying to make a couple small rear bags, and he actually took the time to talk to me about how to do it, and then sent me some scrap material that he had for free! Great guy, helping other shooters and the community. Only way to go, unless you order that thing off amazon that was made in China.
