@checkervest There was hammering in the loft workshop. There was cutting and testing and prototyping and a montage of piles of increasingly-workable netting mounts made from tent pegs, spare clamps and curtain rails. A plantation of tea was drunk and many a buttered crumpet to follow. The prototyping complete, finished products came off the assembly line. They clamped to the edge of the paving slabs lining the pond and held the netting high and taught. Surely no shenanigans could penetrate this.
