Surround for a preformed pond
My husband dug the hole in the summer and fitted a preformed pond. It has an undulating shape. My problem is how to surround it so that the edge is neatened up because at the moment it is getting warped and doesn't look very attractive. He has just bought some paving slabs but is now agonising about how best to fit them. Any ideas please. I have completed many searches on the internet and found very little inspiration.
