Our patio runs along the whole back wall of the bungalow. There is about a 4" gap between the first lot of slabs and said wall. We currently have it lined with gravel from the driveway:
We took the decision to change it. DB cleared out the gravel and soil down to about 2", cut up some old compost bags into strips, pushed them well down front and back before temporarily holding them in place with a few stones:
It just looks so much better and now, we will only have to sweep the red gravel from the patio back to where it belongs. Much easier!
