Hi Angie, I think it was out at the Mahomet botanic garden at Lake of the Woods in their childrens garden. I thought it had just cucumbers. Im trying to picutre where the tomaotes fit in to the system without being too crowded by the vines of the cucumber. I think your idea is sound to use for any vining crop such as peas, cucumber or squash. You can make them whatever dimensions fit your area. however the taller the trellis the more durable it will have to be especially how it is secured to the ground. perhaps with rebar or if not too tall with doggie curliy q stakes. I dont have any drawings but I suspect you can go online and find one that fits your area. Happy gardening. Sandy
