Hi. There are several cover makers who will do made to measure. I had one made by Scratch and Newton and although the quality is extremely good I never used it after the first season because I found that during torrentail rain the water tended to pool on one area, and the weight of that water caused the mesh on my run lid to bend. Now I just use a big board (3'X3' ) with which I cover one corner of the lid. This gives plenty of cover and I've another board which I position along part of the side which means that they have one area which is water and wind proof. I reckon this is a lot easier than having to deal with sopping wet run covers.
