Hi all! I hope this is a good place to post this.
I decided to make a raised bed garden and start growing our own vegetables. I researched online for what seemed like forever, including reading through posts here. Unfortunately, I'm a night nurse and often seem to leave my brain at work and start projects when I'm tired. I drew up my plans, obsessed over them for several days, and got to work. I knew I wanted to start with one 4'x8' bed for 32 squares. I came up with a brilliant idea to use the leftover panels from the metal roof we had put on our house. Cutting them was NOT fun. I framed it with 2x4s and it ended up being 22" high after working around the grooves in the roofing panels.
I made it 8'x4' on the OUTSIDE instead of inside the bed.

After accounting for the 2x4s and the metal panels my interior dimensions are about 7'8"x3'7". Of course I didn't even realize until after I filled it, which took forever the way I did it. I even stained it since none of the wood touches the soil.
If I divide it into 32 squares now they are only 11.5"x10.75". I figured that won't work since it's already tight to begin with. I spent all day obsessing over how to make this still work for square foot gardening.
I've attached a quick sketch of how I ended up leaving it for today but any input or suggestions would be very much appreciated. I was planning to build several more identical beds if I did well this year with my first bed. Now if I build new ones they'll either not match or be off like my first one. I know that's no big deal to some people but I have a hard time letting go of silly stuff like that, and I'm upset that I made such a stupid mistake before even getting the garden started.
I was thinking I could do tomato and other larger plants in the four 20"x23" sections. I didn't put the string down the center of the 23" sections because it would have divided the large squares where I'd need to plant, so I figured I would just eyeball for the rest of the 12"x11.5" "squares."
Thanks in advance for any suggestions.
