Ah the tomatoes showing strong support 💪
Nice idea.
If you do tomatoes I highly recommend this type of trellis. Run twine down to the tomato vine and use these plant clips. https://gardening-plant.com/products/100pc-plastic-trellis-tomato-clips-plant-support-vines-veggie-garden-supplies

I stumbled upon a YouTube video of someone doing it a few years back and it’s been my method ever since. So much easier to tend to the tomatoes and they vine up really well.
