I can get this if wanted, it's strong but quite thin so you need to be carefull when gluing it down. If the glues too wet then it may come through the fabric so you'd need to spray your plastic panel, leave it a minute or 2 then apply the fabric.
Because its thin the overall feel will be hard, basically resting your arm on the plastic panel with a thin layer of fabric inbetween. Mine was done with a 3mm foam first so its soft but wasnt easy to do
The fabric is a great match for the DC2 and EK9 recaros and the quality is spot on. It comes in lengths of roughly 1M x 1.4M so you'd have plenty to practice with on a EK. Price would be roughly £20 + postage
