About four years ago that basket was full of peaches I bought at an orchard. I have no idea if it was made with recycled cardboard or not. I have four of them that I keep in the garden shed for picking stuff. Never let a good basket go to waste!
If you grow pole beans instead of bush beans you can save a lot of space. And space-wise you can get more on a trellis than you can a tri-pod or quad-pod tepee. Pole beans will grow up to the moon but I make the trellises only as tall as I can reach to pick. The beans will run to the top and then start running down again.
I plant bush and pole beans about 2-3" apart. Real bushy bush beans sometimes get planted 4" apart (air flow concerns). You can get away with pole beans 2" apart because, as you can see above, the foliage is thin at the bottom, which will give you 6 plants per row foot.
Beans will grow in full sun but can appreciate a bit of shade during the hottest part of the day. These CTOTs will do fine in the all day sun.
