These new Cuckoo Clock fabric panels from Kristen Doran are just gorgeous. You could turn them into many different things, but I think they are perfect for a statement cushion to sit on an armchair.
The ideal backing fabric would be the organic cotton canvas in red (above). Red is hard to match but this one is pretty close. Some other options are this beautiful textured grey linen to go with the grey/blue colourway. The organic cotton canvas in chocolate or leaf green both match the green colourway really nicely.
