I just finished decking this entry path and it looks amazing. It wasn’t as hard as I thought it would be, which has given me the confidence to start on the longer path.
I cut the slats to 80cm long and waterproofed the underside, then I used decking screws to screw them on. I already had a frame from the PVC plantation shutters left over, so I used that. I then bought some PebbleLock to keep the sides neat when I went to add the pebbles.
