I do enjoy this thread! 5 yards of garden soil, I have to move to my 10K sq foot double city lot back yard one wheel barrel at a time! I do back up to a 5 acre green space with a two acre park, so it actually looks much bigger than it is.
And don't worry too much about the lines being perfect, the soil will move them anyway. They'll settle and adjust over the years, it's part of the fun. On my end I put ... I don't know if they call it this anymore, but playground cedar chips down to keep out weeds between the raised beds. Not worth it for your size of garden, but works for me.
Other than the last two days, we've had a historically dry and sunny November in the Pacific Northwest. I built a new trellis yesterday for my peas and beans.
