Cheap landing tape. Take some lounge chair or any type of outdoor material (rope is okay)
If flat material, fold over end and install grommet or melt around the hole. You will need to allow a couple inches extra and start your first mark from the center of the grommet hole. Make a mark every 3 inches
I have them for sale for $20 + $3 shipping CONUS.
